The best headless CMS agency or headless web development partner for your project is the one that recommends the right platform for your context — not the one they are most comfortable with. This guide ranks agencies on verifiable CMS expertise, platform breadth, migration track record, and documented editorial outcomes.TL;DRA genuine headless CMS agency recommends the right platform for each client context; multi-platform production experience and content modeling depth are the two criteria that separate specialists from frontend shops that happen to use a CMSPlatform partnership tiers and listing platform rankings are commercially influenced signals — verified review content describing specific editorial and business outcomes is more reliableKey selection criteria: verified production cases across at least three CMS platforms; content modeling treated as a core deliverable not a configuration task; evidence the agency has recommended against their preferred platform for a specific client; testimonials from editorial stakeholders, not only technical leadsFocusReactive ranks first: six CMS platforms in production, official partnerships on four, vendor-agnostic selection verified across case studiesMid-complexity implementations typically start at $30,000; migrations with content modeling redesign run $50,000–$150,000; enterprise multi-market builds start at $150,000Top 4 headless CMS agencies in 20261. FocusReactive — the most platform-complete headless CMS agency on this list; official partners of Sanity, Storyblok, Contentful, and Payload CMS; production experience on Directus and DatoCMS; genuine vendor-agnostic selection process with a proprietary CMS toolkit refined across dozens of deployments2. Anything Agency — 10+ years headless-only delivery; Storyblok UK & Ireland Partner of the Year; Contentful certified; deep editorial case studies including long-term enterprise partnerships3. Bits Orchestra — .NET and CMS specialist with Kentico Xperience Bronze Partner status plus Contentful, Strapi, Sanity, and Umbraco; strongest for enterprise portal modernisation and B2B organisations in the Microsoft ecosystem4. The Frontend Company — frontend-led headless CMS integration with a documented multi-platform practice across Contentful, Sanity, Strapi, and DirectusIntroStructured content has quietly become the foundation of two of the most consequential shifts in digital right now: editorial teams that can publish, localise, and iterate without raising a developer ticket, and content that surfaces in AI-generated answers rather than only in traditional search rankings. Both outcomes depend less on which headless CMS you choose and more on how deeply the agency implementing it understands content modeling, governance, and the relationship between content structure and machine readability.The headless CMS software market reached approximately $820 million to $1.3 billion in 2024, expanding to an estimated $970 million to $1.5 billion in 2025, according to Future Market Insights. This represents two to three times the growth rate of the overall CMS market.The broader global CMS market stands at approximately $31–35 billion in 2025, according to Mordor Intelligence and Grand View Research, growing at a 7.7–10.6% CAGR through the early 2030s. Within that total, the headless segment is far smaller but far faster-growing.This shift has structural drivers. Gartner requires composability as a mandatory criterion for inclusion in its Magic Quadrant for Digital Experience Platforms, and projects that 70% of organisations will be mandated to acquire composable DXP technology by 2026, up from 50% in 2023. What was a developer preference three years ago has become enterprise infrastructure policy.That change raises the bar for what agencies need to deliver. A team with experience on one headless CMS is not the same as an agency that has selected, migrated to, and governed five different headless platforms across varied client contexts. As the market matures, that distance grows.What makes a legitimate headless CMS agencyMost comparable lists rank each headless CMS development company by Clutch position or platform partner directory placement. Both signals are compromised: Clutch and DesignRush offer paid tier upgrades that influence placement without transparent disclosure, and platform partner status can be acquired for business development purposes rather than reflecting deployment volume or client outcomes. We used review platforms as sources of verified feedback content only — not as ranking inputs.The criteria below are harder to fake and more predictive of outcomes.Multi-platform portfolio (highest weight)A genuine headless CMS agency has delivered real client work across at least three distinct platforms — for example, Contentful, Storyblok, Sanity, Payload, Directus, Hygraph, or Prismic. Agencies that default every client to a single platform are not making advisory recommendations; they are extending their own technical familiarity at the client's expense. Different client contexts require different platforms: a marketing team that needs visual editing independence is poorly served by Sanity's developer-centric studio; an enterprise managing structured content across 20 locales is poorly served by a self-hosted Strapi instance without the infrastructure to support it.Verified client outcomes — reviews and casesWe focused on verified reviews that describe specific content-related outcomes: faster publishing workflows, reduced editorial support tickets, migrations completed without search ranking loss, measurable cost reduction versus the prior stack. Reviews from editorial and marketing stakeholders — not only CTOs — are a particularly strong signal, because they confirm the agency built something that non-technical users can actually operate.Content modeling depthContent modeling — the architecture of content types, fields, relationships, and reusable components that underpins a headless implementation — is where genuine CMS expertise lives. Agencies that treat it as a configuration task rather than a design discipline produce implementations that work on launch day and degrade over the following 18 months as editors encounter the limits of the model.Platform-agnostic advisory evidenceThe strongest signal of client-oriented practice is evidence that an agency has explained when not to use their preferred platform. Published comparison content, case studies with documented platform selection reasoning, and the ability to articulate trade-offs honestly are all relevant markers.Migration track recordCMS migrations stress-test expertise. Moving from a traditional CMS to a headless platform, or from one headless platform to another, requires simultaneous competence in content architecture, data transformation, SEO preservation, and editorial change management. Verifiable migration cases with named clients, named platforms, and described scope are a reliable quality proxy.ial and non-technical stakeholder focusA CMS exists primarily for editors and content managers. Agencies that design for developer convenience but neglect editorial usability deliver technically clean systems that require IT involvement for routine content updates. Case studies mentioning editor training, content governance, and workflow design — and testimonials from marketing or content roles — are positive signals.Comparison table

FocusReactiveFocusReactive is an engineering-led headless CMS agency with official partnerships across Sanity, Storyblok, Contentful, and Payload CMS, production experience on Directus, and a vendor-agnostic selection process backed by documented case studies showing different platforms deployed for different client contexts.OverviewFocusReactive operates across offices in the Netherlands, the United Kingdom, and Poland, delivering across CET and ET timezones. Their work is built around four business outcomes: content systems that stay clean as editor count scales; genuine locale-specific publishing for multi-market organisations; marketing teams that launch campaigns without raising developer tickets; and businesses managing multiple brands from a single content architecture.Content modeling is treated as a primary design discipline rather than a setup task. Structured content types, reusable components, and governance rules are built into the schema from the start — so the system stays editorially consistent as teams and content volume grow. Permission structures, publishing approval chains, and content relationships are designed upfront to prevent structural debt as editorial teams expand.On AI SEO readiness, structured data and Schema.org markup are built into every project from day one. Content models are designed with machine readability alongside editorial usability — explicit entity relationships and clean semantic markup that allows AI crawlers to extract facts and cite the content as a canonical source, not only rank it in traditional search.Key services- Platform selection and content architecture consultancy- Headless CMS development and implementation across six platforms- CMS migrations from traditional and headless platforms- Localisation and multi-market content infrastructure- Next.js frontend development with performance and structured data built in- Technical audits of existing CMS and frontend stacks- Integration with DAMs, marketing tools, and third-party APIsFeatured case study — Arrive (EasyPark)Arrive, a mobility and transportation company, needed to consolidate a fragmented digital presence across multiple markets into a single unified platform that content editors could operate independently — across languages, countries, and product lines — without developer involvement.FocusReactive architected a composable platform on Storyblok and Next.js, deployed on Vercel, with a monorepo built in Turborepo housing a shared UI library, Storybook documentation, and a unified CI pipeline. The content model was built in Storyblok with structured schemas serving both editorial use and external systems. Internationalisation was implemented with dynamic routing and localised content per market.Results: 100+ UI components and 30+ CMS sections delivered; 4 markets served from a single content architecture; 97 Lighthouse performance score; +38% organic traffic post-launch; +61% organic impressions in the first 90 days.CMS platformsSanity, Storyblok, Contentful, Payload CMS, Directus, DatoCMS (official partnerships: Sanity, Storyblok, Contentful, Payload)Strengths- Widest verified CMS platform coverage on this list, with production cases across all six platforms- Explicit vendor-agnostic advisory with published platform comparison content and case studies showing different platforms used for different client contexts- CMS-Kit framework reduces implementation time and risk on common patterns- Content modeling and editorial workflow design treated as primary deliverables alongside frontend delivery- Localisation and multi-market infrastructure as a documented specialism- Offices in the Netherlands, UK, and Poland; CET and ET timezone coverageLimitations- Frontend delivery is Next.js-only — not suited to projects requiring PHP backends, Drupal builds, or Java-based enterprise stacks- No meaningful traditional CMS practice — organisations maintaining a WordPress or Drupal estate alongside a new headless build will need a separate resource for the legacy layer- Cloud-native CMS focus — on-premise or air-gapped deployments for regulated industries are not a documented part of their portfolioBest forOrganisations evaluating which headless CMS to use and wanting a genuine recommendation informed by project requirements.

Anything AgencyAnything Agency is a UK-based headless CMS development company with over a decade of headless-only delivery, Contentful certification, and enterprise case studies demonstrating editorial transformation alongside technical delivery.OverviewAnything Agency has operated exclusively in the headless space for over ten years. Their primary platform is Storyblok, where they hold the UK and Ireland Partner of the Year designation. They also maintain a Contentful practice with Contentful certification, and their integration work spans Algolia for search and Microsoft Dynamics 365 and Salesforce for CRM, giving their delivery scope broader reach than most single-platform agencies.Their client portfolio spans enterprise brands, high-traffic media, and B2B organisations. A 12-year partnership with Netmums — a high-traffic parenting platform — is a marker of long-term editorial usability: a relationship of that duration only persists if the editorial experience continues to serve the team.They publish comparison content between Contentful and Storyblok with genuine trade-off analysis, which is evidence of platform-comparative thinking within their two-platform scope.Key services- Storyblok implementation, governance, and editorial training- Contentful implementation and migration- Discovery and content strategy- CMS migration from Umbraco, WordPress, and other platforms- CRM and search integration (Salesforce, MS Dynamics, Algolia)- Performance optimisation and analytics setupVerified client outcomesAmtico: migration from Umbraco 7 to Storyblok, with sub-1-second load times and a 100% SEO score.

The Frontend CompanyThe Frontend Company builds headless CMS solutions with a documented multi-platform practice across Contentful, Sanity, Strapi, and Directus, with a frontend-led delivery model.OverviewThe Frontend Company works across Contentful, Sanity, Strapi, and Directus with React and Next.js as their primary frontend stack. Their published content includes a headless CMS agency comparison guide. This headless CMS development company positioning is frontend-primary — the headless CMS serves the design and editorial experience rather than the other way around. This is a legitimate approach for a certain class of project, but it means content architecture and editorial governance may receive less emphasis than in agencies where CMS is the primary discipline.Key services- Headless CMS implementation across Contentful, Sanity, Strapi, Directus- Content modeling and CMS integration- Frontend development in React and Next.js- CMS migrations and legacy site modernisation- API integration and third-party connectionsCMS platformsContentful, Sanity, Strapi, DirectusStrengths- Multi-platform CMS portfolio across four headless platforms- Strong frontend and UX capability for design-driven implementations- Solid client review scores and referral rateLimitations- Frontend-primary positioning means content architecture and editorial governance are secondary concerns- Migration track record is less prominent than the top three agencies- CMS depth per platform appears shallower than agencies for whom headless CMS is the primary disciplineBest forOrganisations where the frontend experience is the primary deliverable and headless CMS is the supporting content infrastructure.

Cocoon AgencyCocoon Agency is a UK-based digital agency with 11 years of experience in composable and MACH-aligned architecture, positioning headless CMS within a broader composable stack rather than as a standalone product decision.OverviewCocoon Agency is explicitly platform-agnostic at the philosophy level. Their headless CMS services span technology selection and consultancy, implementation, replatforming and migration, and AI and omnichannel integration strategy. Their case studies cover complex B2B contexts: an intricate data and commerce platform for O2O serving over 4,000 retailers, and a content management transformation for ESG intelligence platform Integrum ESG.Their MACH orientation means they engage with the composable commerce and DXP ecosystem beyond CMS alone — relevant for organisations whose content management challenges are embedded in broader commerce or data architecture questions.Key services- Technology selection and CMS consultancy- Headless CMS implementation and integration- Replatforming and migration with data integrity focus- Composable commerce architecture- AI and omnichannel integration strategy- Custom software developmentCMS platformsSanity (documented primary), composable stack across vendor-agnostic selectionStrengths- Clear MACH and composable architecture philosophy aligned with the enterprise direction of the market- Handles complex B2B and omnichannel cases that simpler headless agencies avoid- 11 years of consistent headless and composable focusLimitations- Publicly documented multi-platform CMS breadth is narrower than the top two agencies — Sanity is the primary evidenced platform- Case study detail is lighter than ideal for procurement decisionsBest forOrganisations pursuing MACH architecture across content, commerce, and data as a unified programme. Complex B2B environments where content management is one component of a broader composable platform.6. Culture Foundry
Culture Foundry is a US-based digital agency with the widest traditional CMS platform coverage on this list, spanning WordPress, Drupal, Craft CMS, Wagtail, MODX, and Django, making them the strongest choice for organisations evaluating the full range of CMS architectural options.OverviewCulture Foundry's technology stack spans WordPress, Drupal, Django, Craft CMS, MODX, Wagtail, and Shopify, alongside GraphQL, Node.js, Python, and Go on the API layer. Their client profile includes 24 Hour Fitness, the NYRA and Belmont Stakes, the LBJ Presidential Library, the Clinton Digital Library, and the American Library Association — editorial-heavy organisations where content governance and long-term maintainability are primary concerns.Their relevance to a headless CMS shortlist is strongest when the decision is not yet settled: organisations evaluating whether to migrate from a traditional CMS, and to what, benefit from an agency that can advise across both traditional and headless options without a structural incentive to recommend the latter.Key services- CMS strategy and platform selection across traditional and headless options- WordPress, Drupal, Craft CMS, MODX, and Wagtail development- Custom headless builds with React.js and GraphQL- Managed hosting and long-term support- Search engineering and custom content applicationsCMS platformsWordPress, Drupal, Django, Craft CMS, MODX, Wagtail (headless: custom React/GraphQL builds)Strengths- Widest traditional CMS platform coverage on this list — genuine advisory capability across multiple architectural approaches- Deep expertise in editorial-heavy, content-governed industries- US-based team across multiple time zones with managed hosting infrastructureLimitations- Not a headless-first agency — organisations that have already committed to a cloud-native headless CMS will find more platform depth elsewhere- Headless-native CMS expertise (Contentful, Storyblok, Sanity) is limited compared to specialistsBest forOrganisations with existing traditional CMS estates evaluating whether and how to migrate to headless architecture.

Pagepro is a Sanity and Next.js specialist with Official Sanity Partner status, a 4.9 Clutch rating from 31 verified reviews, and enterprise clients including Pfizer, Orange Polska, and Ziff Davis.OverviewPagepro is based in Poland. Their CMS delivery is Sanity-first — their platform recommendation does not seem to meaningfully vary by client context, which limits their value as a platform-agnostic CMS advisor but not as a Sanity implementation partner. For organisations that have already selected Sanity, their depth on the platform — GROQ development, custom workflows, and a documented large-scale migration (GPnotebook: 30,000+ clinical articles rebuilt on Next.js and Sanity) — makes them a credible delivery option.Key services- Sanity CMS implementation, GROQ query development, and custom workflows- Next.js frontend development- Legacy CMS migration to Sanity- Contentful and WordPress migration services- Performance optimisation and technical auditsCMS platformsSanity (primary, Official Partner), Contentful, StrapiStrengths- Deepest Sanity platform expertise on this list- 4.9 Clutch rating from verified enterprise reviews- Proven migration track record with named, large-scale clientsLimitations- Sanity-first approach means recommendations are not platform-neutral- Less suited to projects where Storyblok, Payload, Directus, or another platform is the better fitBest forOrganisations that have selected Sanity and need deep implementation expertise. Scale-up and enterprise teams with complex content modeling requirements aligned with Sanity's content lake architecture.Special mentionsThe following three agencies have some relevance to headless CMS projects in specific contexts but ranked outside the main list — either because headless CMS is secondary to a broader practice, platform coverage is narrow, or verifiable headless-specific case evidence was limited.8. DotStark AgencyDotStark is a Kentico-primary agency with Microsoft ecosystem depth across Azure, Dynamics 365, Power Platform, and SharePoint. Their headless CMS services page covers standard service categories without the platform specificity or content modeling depth of the ranked agencies. Most relevant for organisations already embedded in Kentico and Microsoft infrastructure.9. SCubeSCube development agency, from New York, operates in contexts where content management intersects with data compliance and enterprise security, with a focus on Strapi and Contentful. Most relevant for fintech, financial services, and compliance-heavy organisations where CMS architecture must account for data residency and security requirements. Note: limited public case evidence was available during research for this article.10. SolGuruzSolGuruz is a custom software development company with AI-assisted engineering. Headless CMS is one integration component within broader platform builds rather than a primary specialism. Relevant for organisations building custom platforms where a headless CMS is one of several moving parts, and development velocity is a priority alongside CMS functionality.How to choose the right headless CMS agencyThe question most buyers get wrongMost organisations approach agency selection with the CMS platform already decided, or with a strong preference formed from a single source. A competent headless CMS agency will push back on a platform choice if the evidence does not support it. If an agency immediately validates your existing preference without asking about your editorial team's technical confidence, your content volume and type, your localisation requirements, or your integration landscape — that is a red flag, not a sign of alignment.In-house versus agencyBuilding headless CMS capability in-house is appropriate when the platform is already implemented, the implementation is stable, and the ongoing work is primarily editorial tooling and maintenance. Agency expertise adds clear value when you are evaluating which platform to use, migrating from a legacy CMS, expanding to multiple markets or channels, or building content infrastructure that your editorial team needs to operate without developer support.Budget ranges for 2026CMS platform selection consultancy only: $5,000–$20,000New headless CMS implementation, mid-complexity, single market: $30,000–$80,000Legacy CMS migration with content modeling redesign: $50,000–$150,000Enterprise multi-market or multi-brand headless infrastructure: $150,000–$400,000+An agency that provides a fixed quote before understanding your content model and integration requirements has not understood your project.Questions to ask before hiring a headless agencyWhich headless CMS platforms have you delivered in production in the last 18 months? Can you name the clients or describe the scope?Have you ever recommended against a client's preferred platform? What was the reason?What does your content modeling process look like, and who leads it — a developer or a content architect?Can we speak with an editorial stakeholder from a past project, not only a technical lead?What happens when editors encounter a use case the CMS model does not support? Self-assessment: do you need a headless CMS agency?Score each question 1–5 (1 = does not apply, 5 = strongly applies):1. Your current CMS requires developer involvement for routine content updates2. You need to deliver content across more than one channel or market3. You are planning a migration from a legacy CMS4. Your team lacks experience in content modeling or API-first architecture5. ial team independence from the development team is a business requirementScore 20–25: agency partnership is strongly indicated.
Score 12–19: consider agency support for setup and migration phases with in-house handover.
Below 12: in-house implementation is viable with guidance.Red flagsThe agency's own website runs on the same CMS they recommend for every clientCase studies only mention frontend metrics with no editorial or content outcomesAll testimonials are from developers or CTOs — none from editorial or marketing stakeholdersThe agency cannot explain the trade-offs of their recommended platform against its alternativesPlatform partnership status is the primary evidence offered for expertiseWhat does a headless CMS agency do?A headless CMS agency designs, implements, and governs API-first content management systems — platforms where the backend content store is decoupled from the frontend presentation layer. Content lives in structured fields delivered via API, and the frontend is built independently using whatever framework the project requires.In practice this covers: platform selection and advisory; content modeling (designing the content types, fields, relationships, and reusable components that will underpin the editorial experience); implementation and configuration; integration with commerce platforms, DAMs, CRM systems, and search tools; migration from legacy CMS platforms; editorial training and workflow design; and ongoing governance and maintenance.The distinction between a headless CMS agency and a web development agency that uses a headless CMS is meaningful. Most development agencies have one or two default platforms they apply consistently. A headless CMS specialist has deep production experience across multiple platforms, treats content architecture as a primary deliverable, and makes platform recommendations based on the client's editorial and technical context.Headless versus traditional CMS: the practical differencesA traditional CMS couples content management with the presentation layer. The CMS generates HTML, controls page templates, and determines how content is displayed. This makes initial setup fast — but creates rigidity at scale. Changing the frontend requires changes to the CMS. Delivering content to a mobile app, a voice interface, or a second regional website requires duplication or workarounds.A headless CMS removes that coupling. Content is stored in structured fields and delivered via REST or GraphQL APIs. This frontend-first model is often described as headless web development, where websites and applications consume content from the CMS via APIs rather than being generated inside the CMS itself. Multiple frontends can draw from the same content store. ial and development teams can work in parallel. Platform upgrades on either side do not require simultaneous changes to the other.The practical benefits for 2026 deployments: faster frontend load times through static generation and edge caching; editorial independence from the development release cycle; structured content that can feed AI-driven personalisation and search; and genuine omnichannel delivery without content duplication.The practical costs: higher initial implementation complexity; content modeling decisions that require more upfront expertise to get right; and editorial experiences that vary significantly depending on platform choice and implementation quality.When to hire a headless CMS agency: Four scenarios1. Legacy CMS migration with SEO and content integrity requirementsOrganisations on monolithic CMS platforms with substantial indexed content face a migration risk that in-house teams frequently underestimate. A poorly executed migration to headless can result in permanent loss of organic search rankings. Headless CMS development companies with documented migration experience manage content transformation, URL mapping, redirect implementation, and structured data preservation as a single coordinated process.2. Omnichannel content delivery across markets or channelsWhen content needs to reach a website, a mobile app, a partner portal, and an internal tool from a single source, the content model must be designed for omnichannel delivery from the start. Retrofitting this into an existing implementation is expensive. An agency that has designed multi-channel content architectures will make different modeling decisions upfront than one that treats the website as the primary consumer.3. ial team autonomy without developer dependencyMany headless CMS implementations are technically clean but practically unusable without developer involvement for routine editorial tasks. Platform selection and content modeling decisions determine whether editors can work independently or whether every page change requires a ticket. Agencies with strong editorial design practice treat this as an architecture problem, not a training problem.4. Multi-market and multi-brand content infrastructureOrganisations expanding into new markets or managing multiple brands on a shared content platform face localisation, governance, and publishing workflow challenges that require deliberate architectural decisions. These include locale-specific content modeling, permission structures for different editorial teams, and content relationships that work across multiple frontends drawing from a shared source.FAQs What is a headless CMS agency?A headless CMS agency or headless CMS development company designs, implements, and governs API-first content management systems where the content backend is decoupled from the frontend presentation layer. A genuine headless CMS agency recommends the right platform for each client context, requiring practical expertise across multiple headless platforms.How is a headless CMS agency different from a web development agency that uses headless CMS?Most web development agencies have one or two default headless CMS platforms they apply consistently. A headless CMS specialist has deep production experience across multiple platforms, treats content architecture and editorial workflow as primary deliverables, and makes platform recommendations based on client requirements rather than tooling familiarity.Which headless CMS platforms are most widely used by specialist agencies in 2026?Contentful, Storyblok, and Sanity cover most use cases. Contentful is strongest for enterprise structured content at scale. Storyblok is strongest when editorial visual editing and team autonomy are priorities. Sanity is strongest for developer-controlled custom content modeling. Payload CMS and Directus are increasingly chosen when the CMS and application need to share a codebase or database. DatoCMS is common in Jamstack and performance-critical deployments.How much does a headless CMS implementation cost in 2026?A new implementation from a headless CMS development company for a mid-complexity site typically costs $30,000–$80,000. Migrations from legacy platforms, especially those involving content modeling redesign, usually range from $50,000–$150,000. Enterprise multi-market or multi-brand projects delivered by an experienced headless CMS development company typically start at $150,000. Platform licensing is separate, as cloud-native headless CMS solutions involve monthly or annual subscription costs that scale based on usage and feature tier.What should I look for in headless CMS agency case studies?The most informative case studies name the platform selected and explain why, describe the content modeling decisions made, document editorial outcomes (publishing speed, reduction in developer dependency, governance improvements), and include technical outcomes (load time, SEO stability through migration). Case studies that only describe the frontend redesign or list technology names without explaining content architecture decisions are not evidence of CMS expertise.Should I select a CMS platform before choosing a headless agency?Not necessarily. If you have a well-reasoned requirement that clearly aligns with a specific platform’s strengths, it can be sensible to choose the platform first and then find a headless CMS development company with deep expertise in it. However, if you are still evaluating platforms, it is often a stronger approach to work with an agency that has production experience across multiple options and can provide guidance without a commercial bias.What is the difference between a headless CMS and a composable DXP?A headless CMS manages and delivers content via APIs. A composable Digital Experience Platform assembles multiple best-of-breed components — content management, commerce, personalisation, search, DAM — into a unified architecture via APIs and a shared data layer. Headless CMS is typically the content management component within a composable DXP. The MACH Alliance framework (Microservices, API-first, Cloud-native, Headless) describes the architectural principles that composable DXPs follow.
This guide is editorially independent. No headless CMS development company paid for inclusion or placement. Platform partnership status was treated as a data point for platform familiarity, not as a ranking signal. Clutch and G2 review data was used as a source of verified client feedback, not as a ranking input.

Choosing the best Next.js agency is one of the highest-leverage decisions a SaaS founder or enterprise engineering lead can make. Regardless of the type of project you plan to undertake an agency—be it a small startup, mid-market SaaS, or a large enterprise—Next.js is your sensible choice for the frontend in 2026.This guide evaluates 15 Next.js development agencies across Europe — covering technical depth, verified CMS partnerships, Vercel platform experience, and documented client outcomes — so you can identify the right Next.js developers for your specific project without relying on rankings that prioritise brand size over delivery evidence.According to the State of JavaScript 2025 survey (13,000+ respondents, sponsored by Google Chrome and JetBrains), Next.js is used by 59% of JavaScript developers, making it the most adopted React meta-framework by a significant margin. Not every agency that lists Next.js development services on their website has built production-grade SaaS platforms with it. This guide focuses on European Next.js agencies with documented delivery at scale.Many well-known companies use Next.js for various purposes, e.g., Nike, Stripe, TikTok, Uber, Wayfair, Notion, and Apple. Thanks to its performance, scalability, and developer experience Next.js works well for enterprise websites, SaaS dashboards, and high-traffic landing pages. It’s also popular for e-commerce platforms, marketing sites, and customer-facing web apps.TL;DR — Top Next.js Agencies to Hire Worldwide Best Next.js agency for comprehensive Next.js development services: FocusReactive — engineering Next.js development agency, official partner of Sanity, Storyblok, Contentful, Payload CMS, strategic experts in headless CMS migrations from legacy platforms to headless architecture; 35-domain multilingual delivery for EasyPark, clients all over the worldBest for performance engineering and App Router migrations: Blazity —  70% LCP improvement for CookUnityBest for large enterprise digital transformation: Dept Agency; Contentful partnerBest for net-new SaaS product builds: Netguru or Boldare; full design-to-engineering lifecycle, strong Clutch track recordBest for custom B2B/B2C commerce platforms: Rigby; Medusa.js specialists for marketplace and multi-tenant buildsBest for ecommerce: Maker's Den, FocusReactive Next.js CMS AgencyBest for design-led SMB and startup builds: Halo Lab; competitive rates, high design qualityKey buying signals to verify before committing to any Next.js development agency: App Router in production (not Pages Router), named Vercel partner status, at least one case study with a measured outcome, and a defined post-launch SLA.Who This Guide Is ForThis guide is designed for marketing leaders, technically skilled CMOs, and decision-makers—CTOs, VPs of Engineering, and hands-on founders at mid-market SaaS companies and enterprise digital teams evaluating a Next.js development agency for upcoming projects.Migrating a legacy platform (WordPress, Webflow, Drupal, AEM) to a headless Next.js architectureBuilding a new SaaS frontend or Next.js website from scratch on the App RouterScaling an existing Next.js codebase that has outgrown the original team's capacityIf you are a marketing director selecting a Webflow agency, or an enterprise procurement team seeking a 500-person outsourcing firm, this selection guide is not the right resource. The Next.js agencies listed here are specialist software engineering teams, not general digital agencies, and the evaluation criteria reflect that difference.How to Evaluate a Next.js Development Agency: 8 CriteriaThese criteria should be applied before reviewing any Next.js agency's portfolio. Outline your project needs for each criterion, then score the agencies based on your requirements — not against each other in the abstract.1. Next.js App Router and React Server Component FluencyAny Next.js agency doing serious work in 2026 should be building on the App Router by default — it is the current production standard and the only model Vercel is actively developing new features for. An agency still defaulting to the Pages Router for new projects, or that cannot clearly explain the Client/Server Component boundary, is working on a deprecated paradigm.Ask your agency: Are your current production projects on the App Router or Pages Router? How do you decide which components are Server Components versus Client Components?Red flag: Defaults to "use client" on most components, or describes App Router as "still evaluating."2. Next.js Rendering Strategy DepthA capable Next.js agency should be able to tell you exactly which rendering strategy — SSG, ISR, SSR, or RSC — applies to each layer of your application and why, including the caching and cost implications of each choice. If the answer is "we use SSR for everything," that is not a strategy, it is a default.Ask your agency: How do you decide between SSG, ISR, and dynamic rendering in an App Router project? How do you handle cache invalidation when CMS content updates?Red flag: Cannot explain the difference between route-level and component-level caching in the App Router.3. Vercel Platform DepthProduction Next.js deployment on Vercel goes well beyond connecting a GitHub repo — it requires managing edge middleware, environment variable scoping, preview deployments, build cost optimisation, and observability tooling. An agency that has only used Vercel's free tier has not encountered the challenges enterprise deployments surface.Ask your agency: Have you managed Vercel enterprise accounts with multiple deployment targets? Have you configured Edge Middleware for geo-routing or A/B testing?Red flag: Cannot describe how they manage Vercel build costs or have never used Speed Insights for production diagnostics.4. Headless CMS Integration as Part of Next.js Development ServicesDeep CMS integration means designing the content model, configuring draft mode for live preview with React Server Components, and ensuring editors can operate independently after handover — not just connecting the API and fetching data. Ask for a certified partnership and a concrete content modelling example, not a list of supported platforms.Ask your agency: Are you a certified partner of the CMS we are considering? How do you implement draft mode with Server Components for live preview?Red flag: Treats CMS setup as a configuration task with no content modelling methodology to show.5. SEO Continuity and Core Web Vitals MethodologyFor platform migrations, organic search equity is a business asset that can be destroyed by poor redirect handling or metadata loss. A qualified Next.js agency treats Core Web Vitals and URL continuity as engineering deliverables from sprint one, not as post-launch cleanup.Ask: How do you handle URL mapping and redirect implementation during a migration? Can you show pre/post Core Web Vitals benchmarks from a previous project?Red flag: Redirects are handled at the end of the project, or the agency cannot produce crawl comparisons from past migrations.6. TypeScript and Code Quality: What to Expect from Senior Next.js DevelopersThe codebase a Next.js agency delivers will be maintained by your internal team or a future agency — TypeScript by default, automated tests, and clear documentation are baseline requirements, not premium extras.Ask your agency: Is TypeScript the default on all projects? What testing framework and coverage standards do your Next.js developers apply?Red flag: Delivers JavaScript-only codebases or has no automated testing in the handover.
ask the programmer meme7. Post-Launch Support and SLA StructureThe first 90 days after launch consistently surface redirect gaps, content model edge cases, and performance regressions. A Next.js agency without a formal post-launch support period and documented SLAs will deprioritise incidents because those hours are unscoped and unbillable.Ask your agency: What are your SLAs for critical production bugs in the first 90 days? Is a retainer model available for ongoing work?Red flag: No formal post-launch support structure beyond "reach out if something breaks."8. Enterprise Delivery EvidencePortfolio logos are not delivery evidence — ask for case studies that name a client, describe the integration complexity, and cite a measurable outcome (Core Web Vitals score, traffic change, time-to-market). An agency that cannot provide this has not delivered at enterprise scale.Ask your agency: Can you share a Next.js App Router case study with similar content volume or language count to our project, including the measured outcome?Red flag: Case studies show design screenshots and describe outcomes as "improved performance" without figures.How Next.js Agencies Were Ranked: MethodologyEvery agency in this list was evaluated against five factors. No agency paid for inclusion. Nextjs agencies ranked higher if they used App Router in production. This was verified through case studies, public repositories, or technical blogs. They also needed to show documented delivery at an enterprise content or traffic scale. Agencies whose public case studies predate the App Router era, or whose documentation suggests primary reliance on the Pages Router, rank lower regardless of brand recognition or team size. They align with how independent reviewers such as top headless CMS agencies and development companies evaluate modern headless and Next.js specialists. FactorWeightSignal UsedApp Router and RSC adoption in productionHighVerified via case studies, public repos, or technical blog postsVercel platform depthHighOfficial partner status, enterprise account evidence, edge middleware usageSEO and Core Web Vitals track recordHighNamed platform certifications; documented content modelling approachHeadless CMS certification and methodologyHighPre/post launch metrics; migration case studies; Metadata API usageEnterprise delivery evidenceMediumNamed clients, measurable outcomes, team scale documentationAgency Comparison MatrixThe matrix below uses factual indicators rather than qualitative labels.

According to the State of JavaScript 2025 survey — 13,000+ respondents, sponsored by Google Chrome and JetBrains — Next.js is used by 59% of JavaScript developers, making it the most adopted meta-framework by a significant margin.Three structural factors explain why Next.js framework has become the default choice for SaaS and enterprise frontend development in Europe specifically.Rendering flexibility within a single framework. Next.js supports SSG, SSR, ISR, React Server Components, and Partial Prerendering within a single project. This means the same engineering team handles performance-critical marketing pages, dynamic SaaS dashboards, and API routes without switching frameworks or splitting the codebase. The App Router, now the default since Next.js 13 and stabilised through versions 14 and 15, has matured into a production-ready foundation that engineering teams are actively building on rather than evaluating.Vercel's edge network for multi-market performance. European SaaS companies typically serve audiences across multiple countries and languages. Vercel's global CDN and edge middleware configuration deliver measurable Core Web Vitals improvements over traditional hosting setups, with direct impact on organic search performance in competitive European markets.Ecosystem maturity. The Next.js integration ecosystem — headless CMS platforms such as React CMS solutions (Storyblok, Sanity, Contentful, Payload), authentication providers (Clerk, Auth.js), commerce platforms (Shopify Hydrogen, Medusa), and observability tooling — has reached a level of maturity that substantially reduces integration risk. Native App Router support for draft mode, the Metadata API, route-level caching configuration, and the Vercel AI SDK for AI-powered features means most production requirements are covered without custom workarounds.Frequently Asked Questions about Next.JS1. What is a Next.js development agency?A Next.js agency is a software engineering company that specialises in building, migrating, and scaling web applications using Next.js — the React meta-framework maintained by Vercel. Unlike a general web development agency, a dedicated Next.js agency employs developers who work exclusively or primarily with Next.js, meaning they have hands-on experience with the App Router, React Server Components, Vercel deployments, and headless CMS integrations. When your Next.js project involves performance-critical rendering, multi-language content architecture, or a migration from a legacy platform, a specialist Next.js agency will make different, and usually better architectural decisions than a generalist team that treats Next.js as one tool among many.2. What does a Next.js agency typically charge in Europe?We can't guarantee 100% accuracy, because everything depends. However, hourly rates for specialist Next.js agencies in Western Europe (UK, Netherlands, Germany) range from $80 to $150. Central European agencies (Poland, Ukraine) typically range from $40 to $100. Total Next.js project costs for a headless CMS migration or a new SaaS marketing site range from $30,000 to $200,000+ depending on content volume, language count, integration complexity, and post-launch support requirements. A Next.js project that involves multiple languages, CMS editorial workflows, and Vercel enterprise deployment will sit toward the upper end of that range regardless of the agency's day rate.
3. What is the difference between the App Router and Pages Router, and why does it matter when hiring a Next.js agency?The Pages Router is Next.js's original routing model, where each file in /pages becomes a route and data fetching happens via getServerSideProps or getStaticProps. The App Router, introduced in Next.js 13, uses a /app directory, supports React Server Components natively, and fundamentally changes how layouts, data fetching, and caching are structured. Vercel is actively developing new features (Partial Prerendering, improved caching primitives) exclusively for the App Router. A Next.js agency still defaulting to the Pages Router for new Next.js projects in 2026 is building on a model that will require migration in the near term — and signals they are not actively working at the current production standard.4. What built-in features does Next.js provide to improve SEO?Next.js aligns its rendering and optimisation defaults with what search engines and Core Web Vitals reward, making good SEO the path of least resistance rather than a bolt-on. The key mechanisms are:SSR and SSG deliver fully rendered HTML to crawlers, unlike client-side React apps that ship an empty <div>. Search engines index pre-rendered content far more reliably.The Metadata API (app/layout.tsx or generateMetadata()) lets you define <title>, <meta description>, Open Graph tags, and canonical URLs declaratively — per page or dynamically based on route params:export async function generateMetadata({ params }) {    return {      title: `Product: ${params.slug}`,      description: "...",      alternates: { canonical: `https://example.com/products/${params.slug}` },    };  }Automatic sitemap.xml and robots.txt are generated via convention-based files (app/sitemap.ts, app/robots.ts), keeping them dynamic and always in sync with your routes.Image optimisation via <Image> enforces correct sizing, serves modern formats (WebP/AVIF), and adds width/height attributes automatically — directly improving LCP and CLS scores.Font optimisation via next/font eliminates layout shift from web fonts by inlining font-face declarations and preloading — directly improving CLS.Streaming and React Server Components reduce TTFB and improve LCP by sending HTML progressively, benefiting both users and crawlers.Structured data (JSON-LD) is injected as a <script> tag in any Server Component, enabling rich results in search.A qualified Next.js agency treats all of these as standard delivery requirements, not optional enhancements.5. What headless CMS platforms work best with Next.js in 2026?Sanity, Storyblok, Contentful, and Payload CMS are the four platforms with the deepest documented Next.js App Router integrations. Sanity and Storyblok have native visual editing and draft mode support for React Server Components. Payload is a TypeScript-first, self-hostable CMS that can be run within the same Next.js application. The right CMS choice depends on editorial workflow requirements, content model complexity, localisation needs, and whether the team wants a hosted or self-hosted solution.6. What should a Next.js agency deliver at project close?A production-quality handover from a Next.js agency includes: a TypeScript codebase with automated tests (unit, integration, and ideally end-to-end); documentation covering content model schema, component architecture, and deployment processes; redirect mapping validated against the pre-launch crawl; a configured Vercel project with environment variables scoped correctly to staging and production; editor training and documentation for the CMS; and a defined post-launch support period with documented SLAs for critical and non-critical issues.7. When should I hire a Next.js agency instead of a freelancer? A freelancer is the right choice when scope is tight, the project is well-defined, and you need one or two specific skills — a performance audit, a CMS integration, a specific component build. A Next.js agency makes more sense when the project has moving parts that require multiple disciplines at once (architecture, frontend, CMS configuration, DevOps, QA), when the stakes of getting the architecture wrong are high, or when you need continuity after launch.

TL;DR: CMS Migration Numbers That Tell the StoryMost website migrations fail the same way: rankings drop, traffic disappears, and recovery takes months. The teams that avoid it don't get lucky — they treat CMS migration services as an engineering discipline, not a one-time technical event. The difference between a migration that compounds into growth and one that unravels six months post-launch comes down to how early SEO planning enters the process.The headless CMS market reached $816M in 2024 and is growing 22% annually, with 73% of enterprises already adopting headless architecture. As more companies move to API-first stacks, choosing the right CMS migration service is critical to:Preserve search rankings with proper redirects and URL mappingImprove performance and Core Web VitalsEnable faster content workflows with headless CMSReduce long-term CMS costs and vendor lock-inThis guide reviews the best CMS migration service providers in 2026 to help you migrate safely — without traffic loss or technical debt.Migrate a Website-Growing TrendAnalysts now expect the majority of digital teams to move away from page-based suites toward composable, API-first stacks in the next 2-3 years. As brands add channels, markets, and campaigns, traditional CMS workflows start to crack: content is duplicated per site, templates are hard to change, and every new experiment needs a developer. Headless CMS flips that: content lives in one structured hub, feeds every channel via APIs, and lets editors ship updates without queuing behind the sprint board. When teams rush into a headless CMS migration without SEO planning, they don’t just change platforms; they wipe out the very signals search engines use to trust and rank their sites.What Is Headless CMS Migration? Migrating a website to a headless CMS means decoupling your content from how it's presented. s work in one central content hub. Developers build fast, flexible frontends in Next.js, React, or whatever the delivery layer demands for any channel: web, app, or in-product UI. The content model stays stable. The presentation layer becomes a technical decision, not a CMS constraint.That separation is the point. It's also where migrations get complicated.Your SEO won't migrate automatically. Rankings follow decisions — specifically, the ones you make before anything moves. Keep URLs as stable as possible. Build a complete 301 redirect map for every URL that changes. Crawl both the old and new versions of the site before launch to catch missing metadata, lost content, broken internal links, and orphaned pages. That decision compounds: a redirect missed at migration can take months to recover from in search.The architecture is the easy part to get excited about. The unglamorous audit work is what protects everything you've already earned.Why Go Headless? CMS Migration JustificationWhat pushes businesses to CMS migration besides the draconian price of your Contentful? Let me guess, the code quality? Security reasons? It depends.That's exactly what professional headless CMS migration services are designed to solve — handling the technical and SEO complexity so your team doesn't have to.Here are the top 9 reasons businesses seek headless CMS migration services, starting with economic ones and followed by technical website reasons:Escape runaway license costs: Legacy and monolithic CMS platforms keep increasing base subscription fees. Ballooning costs, driven by user-seat pricing and add-on charges, are turning your content stack into a fixed cost that grows faster than your traffic or revenue. This erodes ROI over time and makes staying on your current CMS increasingly hard to justify.Stop paying for “empty” overages: Many enterprise CMS contracts charge extra for API calls, environments, locales, or storage, even if you’re not using advanced features that justify the bill.Replace complex pricing with predictable value: Moving to a modern headless stack lets you choose components (CMS, hosting, search, media) that match your actual usage and budget, instead of being locked into one vendor’s bundled pricing.Reinvest license spend into growth: The money currently tied up in inflated CMS subscriptions can be redirected into content production, SEO, and experimentation that measurably drives revenue.”Future‑proof against price hikes: A composable headless architecture gives you leverage; if one vendor’s pricing becomes unreasonable, you can swap it out without rebuilding your entire site.Security vulnerabilities: Traditional monolithic CMS platforms like WordPress (when unmanaged) or aging proprietary systems are prime targets for hackers. Outdated plugins, unpatched cores, and shared databases create attack surfaces that headless, API-first architectures simply don't have.Poor performance: A slow website is a leaking revenue pipe. If your CMS is tightly coupled to your frontend, every design tweak becomes a developer ticket. Businesses migrate to gain speed, better Core Web Vitals scores, and the freedom to optimize independently.Technical debt: Years of patched plugins, custom workarounds, and legacy integrations quietly accumulate until your codebase becomes a house of cards. A full site migration is often the cleanest escape route.Lack of scalability: When your CMS can't handle traffic spikes, multiple languages, or omnichannel delivery without expensive custom work, growth itself becomes the enemy. Modern headless platforms are built to scale without breaking.The Moment Teams Start Looking for a Website Migration AgencyMost teams don't reach out to website migration companies because the technology stopped working. They migrate because the cost of staying finally outweighed the cost of moving. The CMS that made sense three years ago — reasonable at the time, familiar to the team, integrated into the workflow — quietly becomes the thing that slows every campaign, blocks every experiment, and shows up as a line item that's hard to justify at budget review.The shift is rarely dramatic. It's the accumulation of small frictions: a developer ticket for a content change that should take thirty seconds, a performance audit that points back to the platform, a pricing renewal that arrives with a number that no longer matches the value. At some point the question changes from "should we migrate?" to "what were we waiting for?"That's when the search for website migration companies begins — not in crisis, but past the point where staying is the safer option.The world of content systems has changed, just like you after Covid. While platforms like Storyblok are popular among marketers for visual editing, the best CMS depends on your team structure, developer resources, and content complexity. Alternatives like Contentful, Sanity, and Strapi may be better suited depending on the use case. We advise Storyblok for its simplicity, as it's the CMS that consistently gets the least pushback from the people who actually use it daily.

How do you move a site without significant SEO loss, and who can assist my team with CMS migration services?What should be taken into account before CMS migration?One of the most critical decisions, besides choosing website migration company, is choosing the right CMS, and for most businesses today, that means going headless. But raw headless power alone isn't enough; consider the following:CMS Flexibility: When you migrate a website, whether from a legacy platform or decide to migrate a WordPress website to a more scalable architecture, clients increasingly demand a CMS that supports diverse, flexible layouts for individual content types. Think distinct page structures for blog posts, case studies, landing pages, and product pages, all managed from a single platform without duplicating effort.Friendliness: The days of requiring a developer to publish a paragraph or rearrange a section are over. The best modern CMS platforms integrate a visual page builder directly into the interface, empowering marketing and content teams to construct, update, and iterate on pages entirely independently — a capability that WordPress alone, in its traditional form, often struggles to deliver at scale.SEO Preservation: A poorly executed migration can wipe out years of hard-earned organic rankings overnight. Careful URL mapping, redirect management, and metadata migration are just as important as the technical build itself — and should never be an afterthought.Localisation Support: For any business operating across borders, localization is no longer a nice-to-have. The ability to manage multiple languages, regional content variations, and locale-specific SEO from within the same CMS is now a baseline expectation, not a premium feature.Get these four right, and your website migration becomes a launchpad; get them wrong, and it becomes a liability.SEO Preservation: The Part That's Easy to Get WrongWebsite migration impacts SEO reasonably. Every page you've ranked took time. Every backlink pointing at a specific URL is a signal you've earned. When you migrate a website, that equity doesn't transfer automatically; it follows the decisions you make before a single line of code changes.The analogy is here: fixing SEO after a website migration is like correcting old handpoke tattoos done by an amateur. You can do it, but you're always working against what's already there. The cleaner move is to plan and protect everything upfront.That means treating SEO preservation as an engineering problem, not an afterthought.Before any migration begins, a serious team runs a full technical audit: title tags, meta descriptions, headings, and image alt text – and documents every URL in the existing site. Not most of them. Every single one. From there, a complete 301 redirect map is built, mapping each old URL to its new destination. Nothing gets left to assumptions.CMS Migration ChecklistThe pre-migration checklist that compounds into your post-launch performance:Full technical audit of the existing siteComplete URL inventory301 redirect map (old URL → new URL)Analytics baseline exportInternal linking structure documentationCurrent ranking data exportSchema markup documentationFull site backup before anything movesMiss one of these, and you're not migrating a website (CMS); you're rebuilding your search visibility from scratch. The development agencies that get this right treat the checklist above as the floor, not the ceiling.
The post-launch CMS migration checklist:Organic traffic monitoring via GA4 and Google Search Console from day one. Ahrefs if you want a second signal.Crawl error checks in the first 48 hours — redirect failures and orphaned pages surface fast if you're watching.Ranking position tracking — flag significant drops in the first two weeks. The faster you catch them, the less they compound.Metadata review in the first month — rewrite underperforming title tags and descriptions while the index is still settling.Index coverage report — confirm priority pages are being crawled and indexed correctly.This combo of technical care and content parity lets you migrate a website to a headless content management system for performance without sacrificing your past merits.Replatforming vs. Migration. Why ''just replatforming' is Not Enough“Just replatforming” is not enough because it moves your site to new tech without accurately fixing the underlying problems in content, workflows, data, and SEO. If you simply swap CMS platforms or hosting and keep the same messy content model, fragmented data, and ad‑hoc processes, you end up with the same bottlenecks. The difference is that only now they’re running on a newer, more expensive stack. A meaningful website migration is an opportunity to rethink information architecture, streamline content types and workflows, clean and normalise data, and plan SEO and analytics from the start so your team actually ships faster and your site performs better instead of “lifting and shifting” old issues into a shiny new interface.How Long Does it Take to Migrate a Website?Migrating a website is rarely a one-size-fits-all process. Migration timelines vary widely depending on the size, complexity, and condition of your existing setup. A simple CMS migration for a small site might take as little as two to four weeks, while a full global website migration involving thousands of pages, multiple languages, and complex integrations can take anywhere from three to six months. Headless CMS Migration Process and PlanningWhen you move a website from a legacy platform to a headless CMS solution, the bulk of the time goes into content mapping, URL redirects, SEO preservation, and quality assurance, not just the technical build. For instance, WordPress migrations tend to be faster thanks to a mature ecosystem of tools, but enterprise-scale projects demand far more planning. Working with a professional CMS migration service can really make a difference. Website migration team have established workflows that help lower risks, safuguard your search rankings, and minimize downtime. No matter if you need basic website migration services for a small business or a complicated content overhaul across different region for enterprise business, the key principle remains unchanged:The more thorough your plan for a migration, the smoother it will be.Top 11 Website CMS Migration Services to Future-Proof Your WebsiteHere's a list of headless CMS migration services that cater to different business needs, covering everything from consulting and maintenance to migrating custom features and integrating AI.1.

The language signals ambition but not specificity. How to Choose the Right CMS Migration ServicesNot every agency that calls itself a CMS migration partner/provider is built for the same problem. Before you shortlist anyone, check these five things:Technical stack expertise: do they know the platform you're moving to, or are they learning on your project?E-commerce experience: product data, payments, and checkout flows don't survive a careless lift-and-shiftCMS specialists vs. generic dev shops: specialists know what breaks, what compounds, and what to protectSEO-safe methodology: redirects, canonicals, ranking preservation — this should be a defined process, not improvised per projectPost-launch support: what happens at week three when something misfires? The answer tells you more than the proposal doesHeadless CMS Agencies QuickpickThis list is very general, as there is no single winner or 'best' CMS service/agency across all scenarious. Everything depends on your site architecture, team structure, and risks around SEO. With that in mind, choose:

If you're planning a migration or specifically looking for a headless CMS agency, talk to CMS migration services team. Here you can also book an SEO-safe migration audit. We'll map out exactly what needs protecting before anything moves. CMS Migration Service FAQWhat happens when you migrate a website?When you run a website migration, you move key elements like domain, CMS platform, URL structure, design, and content from one setup to another. If it’s not planned properly, this can temporarily affect organic traffic, rankings, and tracking while search engines discover and re‑evaluate your new pages.Is SEO migration necessary?Yes, SEO‑led website migration services are essential if you want to keep your existing visibility, rankings, and revenue. Without structured SEO migration work (redirect mapping, content parity, technical checks), you risk broken URLs, lost authority, indexation issues, and significant drops in traffic.Can I migrate from WordPress to a headless CMS without traffic loss? You can migrate a WordPress website to a headless CMS with minimal or no lasting traffic loss if you treat it as a full SEO website migration project. That means preserving high‑value URLs where possible, implementing page‑level 301 redirects, maintaining or improving content, and launching on a fast, SEO‑friendly front end.Do I need e-commerce CMS migration services for Shopify/BigCommerce?If you are moving an e-commerce shopfront on Shopify or BigCommerce to a headless architecture, we recommend e-commerce CMS migration services. They help you migrate product data, content, URLs, and SEO signals correctly so you can benefit from faster headless experiences without sacrificing organic traffic or conversion rates.What headless CMS is the best for a marketing team with limited dev support?Storyblok is the best CMS here, for pure editorial independence out of the box. Its visual page builder lets non-technical teams build and publish pages without a developer in the loop.

ChatGPT’s Shopify integration enables in-chat shopping, but merchants lose control over branding, data, and margins. This article introduces an SDK for building custom ChatGPT shopping assistants with full ownership and zero commission.ChatGPT now has native Shopify integration — product recommendations, in-chat checkout, the works. It's a strong proof of concept for conversational commerce. But once you look closer, the tradeoffs become clear: a 4% commission on every sale, zero control over how ChatGPT presents your brand, and no access to the conversation data that would actually help you optimize.At FocusReactive, specialized headless ecommerce agency, we built an SDK that solves all of this. It lets you create a custom ChatGPT App — a purpose-built shopping assistant connected directly to your Shopify store via MCP, with interactive product components, full AI behavior control, and no commission taken. You keep your data, your brand, and your margins. This article breaks down how it works and why we made the technical decisions we did.Originally published at FocusReactive Blog.TLDR: What This SDK DoesOur SDK lets you build a custom ChatGPT App — a branded shopping assistant that lives inside ChatGPT — connected directly to a Shopify store. Instead of relying on OpenAI's generic product recommendations and Instant Checkout (where OpenAI controls the experience and takes a 4% cut), the merchant gets their own ChatGPT App with full control over how the AI presents products, handles conversations, and drives conversions.What you get:Product discovery via natural language✅✅Interactive product cards (images, variants, swatches)Limited✅ Full MCP UI componentsBranded experience inside ChatGPT❌ Generic ChatGPT✅ Custom ChatGPT App per merchantConversion attribution❌ Black box✅ Full visibilityTransaction fees to OpenAI4% per sale0%Cart and checkout flowSingle-item, redirectsFull cart, native checkoutCustomer data ownershipShared with OpenAI100% merchant-owned
Why Not Just Use the Native Integration?This isn't contrarianism for the sake of it. The native ChatGPT shopping integration is genuinely impressive for what it is — a new discovery channel. But for brands building serious e-commerce experiences, it has fundamental limitations.
Limited Control Over AI-Generated ResponsesChatGPT responds to shopping queries based on its pre-trained models and whatever product data it can access from Shopify's catalog. Merchants have little to no control over how products are presented, described, or compared. ChatGPT might describe a luxury skincare product the same way it describes a budget alternative. It might fail to mention a key differentiator.For brands that have spent years crafting their positioning, handing product presentation to a generic AI model is a non-starter.With our SDK, the system prompt is fully customizable per merchant. The AI knows the brand guidelines, which products to prioritize, how to handle competitor comparisons, and what language to avoid. It's the difference between a knowledgeable brand ambassador and a well-meaning stranger who read the product feed.
Attribution Gaps in Conversational ConversionsWhen a customer discovers and purchases a product through ChatGPT, assessing AI-driven performance is nearly impossible without proper reporting. ChatGPT can send traffic and facilitate in-chat sales, but the merchant has no visibility into what queries led to conversions, which product descriptions performed well, or how the AI influenced the buying decision.Our SDK captures the full conversation funnel: what the customer asked, what the AI recommended, which products were viewed in the interactive cards, what was added to cart, and what converted. This data feeds directly into the merchant's existing analytics stack. No guessing. No attribution gaps.
Data Privacy and Security ComplianceIntegrating Shopify with ChatGPT means customer interaction data flows through OpenAI's infrastructure. For merchants operating under GDPR, CCPA, or industry-specific compliance requirements, this creates real legal exposure. Customer queries often contain personally identifiable information — sizes, preferences, health conditions (for supplements or cosmetics), shipping addresses mentioned in conversation.Our SDK keeps conversation data within the merchant's own infrastructure. The custom ChatGPT App connects to the merchant's backend, not OpenAI's generic shopping pipeline. The data pipeline stays first-party. No third-party data sharing. No compliance surprises.
The 4% Commission ProblemOpenAI charges merchants a 4% fee on every sale completed through ChatGPT's Instant Checkout, on top of Shopify's existing transaction and payment processing fees. For context, that pushes total platform costs close to 7% per sale before fulfillment, shipping, returns, or customer support.For high-volume merchants, that 4% is significant. A store doing $1M/month through ChatGPT would pay $40,000/month to OpenAI alone — not for traffic, not for ads, just for the privilege of the checkout happening inside ChatGPT's interface rather than on the merchant's own site.Our SDK eliminates this entirely. With a custom ChatGPT App, the merchant controls the shopping experience. Checkout redirects to the merchant's own Shopify store. The merchant pays their normal Shopify fees and nothing more.
Architecture: How It WorksThe SDK is built on four core technologies: ChatGPT Apps (OpenAI's custom GPT/app platform) as the conversational interface, MCP UI for interactive commerce components, Shopify Storefront API for commerce data, and Next.js for the backend orchestration and optional website embedding.

The MCP UI LayerThis is the piece that makes conversational commerce actually work for shopping. Traditional chatbots return text. Text is fine for answering questions about return policies. It's terrible for selling products.MCP UI extends the Model Context Protocol to return fully interactive UI components instead of just text responses. When a customer asks "show me running shoes under $150," the AI doesn't return a text list — it returns rendered product cards with images, variant selectors, price displays, and "Add to Cart" buttons.Our SDK uses Shopify's MCP UI implementation with custom components tailored to each merchant's design system. The components are delivered as sandboxed iframes with an intent-based messaging system:Customer asks a question → The chat widget sends the query to the orchestration layerAI processes the query → OpenAI interprets the intent and determines which Shopify data to fetchMCP server returns data + UI → The Shopify MCP server returns product data along with embeddable UI resourcesComponents render in chat → Interactive product cards appear inline in the conversationCustomer interacts → Clicks on a variant, changes a size, hits "Add to Cart"Intents bubble up → The component sends an intent (e.g., add_to_cart) back to the AI agentAgent processes the action → The AI executes the cart operation via Shopify's API and confirmsThis intent-based architecture is critical. The UI components don't directly modify state. They declare what the user wants to do, and the AI agent mediates. This keeps the AI in control of the conversation flow while delivering a rich, app-like shopping experience.Shopify Integration via MCP ServerThe SDK connects to Shopify through a dedicated MCP server that exposes the store's commerce data to the AI agent. This isn't a generic API wrapper — it's a context-aware interface that gives the AI structured access to:Product catalog: Full product data including variants, pricing, availability, images, metafieldsCart operations: Create carts, add/remove items, apply discount codes, calculate totalsStore policies: Shipping, returns, FAQ content — so the AI can answer operational questions accuratelyOrder management: Track order status and process returns for logged-in customersInventory: Real-time stock levels to prevent the AI from recommending out-of-stock itemsEach merchant storefront gets its own MCP server endpoint, configured with their specific catalog, policies, and business rules.E-Commerce Platform Agnostic by DesignWhile this article focuses on Shopify — because it's the integration we've built and shipped first — the SDK architecture is deliberately e-commerce platform agnostic. The AI orchestration layer doesn't speak "Shopify." It speaks a generic commerce interface: search products, get product details, manage cart, initiate checkout, check order status, retrieve store policies.Shopify is one implementation of that interface, connected via MCP. The same pattern applies to any commerce backend:┌─────────────────────────────────────────────────┐ │ AI Orchestration Layer │ │ (platform-agnostic) │ └──────────────────┬──────────────────────────────┘ │ Commerce Adapter Interface │ ┌──────────────┼──────────────────┐ │ │ │ ┌───▼────┐ ┌─────▼─────┐ ┌───────▼────────┐ │Shopify │ │BigCommerce│ │ Commercetools │ │ MCP │ │ adapter │ │ adapter │ │ ✅ │ │ (planned)│ │ (planned) │ └────────┘ └───────────┘ └────────────────┘ We started with Shopify because it's where the majority of our agency clients operate and because Shopify's MCP ecosystem is the most mature in e-commerce. But the adapter pattern means we can extend to BigCommerce, Commercetools, Medusa, Saleor, or any headless commerce platform with an API — without rewriting the AI logic, conversation flows, system prompts, or frontend components. The commerce backend becomes a swappable dependency, not a hard-wired integration.The AI Orchestration LayerThis is the backend that powers the ChatGPT App. It's built with Next.js and serves as the bridge between ChatGPT's conversational interface and the Shopify store. The orchestration layer handles:Tool routing: The AI uses function calling to decide when to search products, when to add items to cart, when to show a product card, and when to just answer a question in text. The orchestration layer routes these tool calls to the appropriate MCP server endpoints.Conversation state management: Shopping conversations are stateful. The AI needs to remember what the customer has already looked at, what's in their cart, and what preferences they've expressed. The orchestration layer maintains this state across the conversation session.Streaming responses: Product recommendations stream in real-time, with MCP UI components rendering progressively as the AI processes the query. No waiting for the full response to load.Next.js Backend & Website EmbeddingThe Next.js application serves two purposes. First, it's the backend for the ChatGPT App — handling API routes, MCP server communication, and system prompt logic. Second, it enables embedding the same conversational experience as a chat widget on the merchant's own website.When embedded on the storefront, the widget handles:Responsive chat interface that matches the merchant's design systemMCP UI component rendering with sandboxed iframes for securityCart synchronization between the chat widget and the main storefront cartAuthentication passthrough so logged-in customers get personalized recommendationsThis means the same AI assistant — same product knowledge, same MCP UI components — works both as a standalone ChatGPT App and as an embedded widget. Customers can discover the brand through ChatGPT or interact with the assistant directly on the merchant's site. The experience is identical.MCP UI Component CustomizationMCP UI doesn't lock you into pre-built templates. The components rendered inside the chat are standard React components — you can build literally anything you want with any styling approach. Tailwind, CSS Modules, styled-components, vanilla CSS, a full design system — it all works. The components are delivered inside sandboxed iframes, so they're fully isolated and don't conflict with the host environment.This means product cards, cart widgets, comparison tables, size guides, lookbooks, promotional banners — whatever the merchant's shopping experience demands — are all built as React components with complete creative freedom:// This is a real React component rendered inside the chat via MCP UI // You have full control — any JSX, any styles, any interactivity const ProductCard = ({ product, onAddToCart, onSelectVariant }) => { const [selectedVariant, setSelectedVariant] = useState(product.variants[0]); const [imageIndex, setImageIndex] = useState(0); return ( <div className="font-brand bg-white rounded-2xl shadow-lg overflow-hidden"> <ImageCarousel images={product.images} activeIndex={imageIndex} onChange={setImageIndex} /> <div className="p-6"> <h3 className="text-xl font-semibold tracking-tight"> {product.title} </h3> <div className="flex gap-2 mt-4"> {product.variants.map((variant) => ( <button key={variant.id} onClick={() => { setSelectedVariant(variant); onSelectVariant(variant); // bubbles intent to the AI agent }} className={`w-8 h-8 rounded-full border-2 transition-all ${ selectedVariant.id === variant.id ? 'border-black scale-110' : 'border-transparent' }`} style={{ backgroundColor: variant.colorHex }} /> ))} </div> {/* Any custom UI — reviews, sustainability badges, you name it */} <SustainabilityBadge score={product.metafields.ecoScore} /> <StarRating rating={product.rating} count={product.reviewCount} /> <button onClick={() => onAddToCart(selectedVariant)} className="w-full mt-6 py-3 bg-brand-black text-white rounded-lg hover:bg-brand-charcoal transition-colors font-medium" > Add to Cart — {formatPrice(selectedVariant.price)} </button> </div> </div> ); }; There are no constraints on what the component looks like or how it behaves. A luxury fashion brand can render a minimalist card with editorial photography and a muted color palette. A sports equipment store can show detailed spec comparison tables with interactive filters. A beauty brand can embed shade-matching swatches with skin-tone previews. Each merchant gets components that look and feel like a natural extension of their brand, not a generic chatbot widget.The components communicate back to the AI agent through an intent-based messaging system — onAddToCart, onSelectVariant, onViewDetails — so the AI stays in control of the conversation flow while the customer interacts with a fully custom UI.Deployment ModelThe SDK ships as an npm package. You use it to build and deploy a custom ChatGPT App connected to a Shopify store. Deployment looks like this:Install the SDK via npm in a new Next.js projectConfigure the MCP server with the Shopify store credentials and catalog settingsWrite the system prompt defining product knowledgeCustomize the MCP UI components to match the merchant's brand and design systemRegister the ChatGPT App with OpenAI, pointing to the Next.js backendOptionally embed the same experience as a widget on the merchant's storefrontDeploy — the ChatGPT App goes live, and if embedded, the widget ships with the next storefront deploymentThe entire setup takes a day for a standard Shopify store. Complex stores with thousands of products, multiple collections, and sophisticated business rules take longer, but the SDK handles the complexity — not the merchant.Hosting and InfrastructureThe Next.js backend runs on Vercel, AWS, or any Node.js hosting. For Vercel-hosted setups (the most common for headless Shopify stores), the orchestration layer runs on serverless functions. The MCP server can be deployed as part of the same application or as a standalone service.ChatGPT App interactions are handled by OpenAI's infrastructure — the backend only processes incoming requests from ChatGPT's function calling. For the optional embedded widget, the same backend serves direct API calls from the storefront.OpenAI API costs are the merchant's responsibility, billed directly through their OpenAI account. For typical e-commerce conversation volumes, this runs significantly less than the 4% per-transaction fee OpenAI charges on native Instant Checkout.What's NextThe current SDK handles the core ChatGPT App shopping experience with Shopify integration. Here's what we're building next:Multi-channel deployment: Extending the same AI assistant beyond ChatGPT and the website — to WhatsApp, Instagram DMs, and email. One system prompt, one MCP backend, multiple touchpoints.Visual search integration: Customers upload a photo ("I want something like this") and the AI matches it against the product catalog using image embeddings. MCP UI components render the results with visual comparison.Post-purchase AI: The same ChatGPT App handles order tracking, returns, and re-engagement. "When will my order arrive?" gets a real-time answer. "I'd like to return the blue sweater" initiates the return flow, all within the chat.The Bigger PictureThe ChatGPT + Shopify native integration is a distribution play. It puts products in front of ChatGPT's hundreds of millions of users. That has value.But for brands that care about their customer experience - the journey, the data, the margin - a custom ChatGPT App is the path forward. You get the distribution of ChatGPT's massive user base with the control of a first-party experience. The AI speaks your brand's language, shows your products the way you want them shown, and you keep every percentage point of margin.Our SDK gives eCommerce brands the technology to build their own ChatGPT App without starting from scratch. Same ChatGPT platform. Full brand control. Zero commission.Tech stack: ChatGPT Apps · MCP UI · Shopify · Next.jsIf you're a merchant and want your own ChatGPT App for conversational shopping, see our custom ChatGPT App serviceFAQHow does this compare to Shopify's own Storefront MCP?Shopify's Storefront MCP provides the data layer — it's the protocol for AI agents to access product catalogs, carts, and policies. Our SDK builds on top of it to create a complete ChatGPT App. For a broader look at how headless architectures fit together, see our headless CMS architecture guide. We add the AI orchestration (with customizable system prompts), the branded ChatGPT App registration, the MCP UI component customization, and the optional website embedding. Think of Shopify's MCP as the engine, and our SDK as the car.Is the SDK limited to Shopify?No. The SDK is e-commerce platform agnostic by design. The core architecture — the AI orchestration layer, MCP communication protocol, conversation state management, and system prompt engine — has no dependency on Shopify. Shopify is the first integration we've built and shipped because it's where the majority of our agency clients operate, and because Shopify's MCP ecosystem is the most mature in e-commerce today.But the abstraction layer between the AI and the commerce backend is deliberately generic. The SDK defines a commerce adapter interface: product search, cart operations, checkout initiation, order tracking, store policies. Shopify is one implementation of that interface. Adapters for other platforms — BigCommerce, Commercetools, Medusa, Saleor, or any headless commerce backend with an API — plug in without touching the AI logic, conversation flows, or frontend components.The same system prompt, the same analytics events. Only the commerce data source changes. If a client migrates from Shopify to Commercetools, the AI shopping experience stays identical — you swap the adapter, not the SDK.What about stores not on Next.js?The core MCP server and AI orchestration layer are framework-agnostic. The chat widget currently ships as a React component optimized for Next.js, but the underlying API can be consumed by any frontend. Hydrogen (Shopify's own React framework), Remix, or even vanilla JavaScript storefronts can integrate with the orchestration layer directly.How do AI costs compare to the 4% commission?OpenAI's API pricing for GPT-4o is roughly $2.50 per million input tokens and $10 per million output tokens. A typical shopping conversation uses around 2,000-4,000 tokens total. That's roughly $0.01-0.03 per conversation. Even if only 5% of conversations convert, and average order value is $100, the AI cost per conversion is well under $1 — versus $4 at the 4% commission rate. The economics aren't even close.Can the ChatGPT App handle multiple languages?Yes. ChatGPT supports 50+ languages natively. The system prompt can include language-specific instructions, and MCP UI components render localized product data from Shopify (which supports multi-language stores). The AI automatically detects the customer's language and responds accordingly.

As it is with many developers, his path to coding was not straightforward. And looking at Shawn's bio, it's apparent he applied that experience to his whole career: he's the head of developer experience at Temporal.io, author of a bestselling book on progressing career in IT, and a sought-after mentor and speaker. His number one advice? “Marketing is not beneath you.”
What led you to software engineering?My first career was in finance, and I did a lot of trading of currency derivatives and stock portfolios. We had to do a lot of number crunching in Excel, Python, and then Haskell. I was the guy putting together all that data. I didn't call myself an engineer, but I was writing software. I saw that there are many good ideas in software engineering that I should learn and that once I do that, my life will be significantly better. So I left finance and went through a boot camp to learn all the software engineering practices. My first job was at two Sigma as a front-end engineer. Then I joined Netlify as a developer engineer and then AWS. What is the most impactful thing you ever did to boost your career?This will sound very similar to Ken's thing, and it's called learning in public. I did it when I was at Sigma because I wasn't learning much at work. I was in New York City, there were many meetups, and I decided to give myself my own mentors speaking there, writing blog posts, sharing them, and just finding more ways to grow apart from inside of my company. And I realized that it was way more effective than just waiting for the right boss or co-worker to teach me.Also, the dev community has been so welcoming and supportive. You learn, share what you've learned, and people will correct you if you're wrong. And once you're wrong, you will never forget what you have been learning. So if you have a pretty thick skin and a low ego, you can learn a lot. In fact, with my most recent job, I wrote a blog post about what I thought was missing in the serverless ecosystem based on what I had seen at AWS and Netlify. Someone commented on my blog, a VC read the comments and hired that guy to head the products at Temporal. And then that guy turned around and hired me based on that blog post. For me, learning in public has opened up jobs and speaking opportunities on multiple continents. And I've made a lot of friends who are genuinely interested in technology.What would be your three tips for engineers to level up their career? Understand that some marketing is unavoidable and that knowing how to market yourself authentically is not scammy. It's not beneath you. It's what you need to do to get people to know you, your skills, and the quality of your work. A lot of developers have a build-it-and-they-will-come mentality, and it does not serve them very well. Invest some time into developing your marketing and understanding how to market yourself. I have a blog called How to market yourself without being a celebrity. When people look at marketing, they see the celebrity path, the influencer path. But many people don't want to be an influencer, so they'll say: "No marketing for me!" Let's disconnect those two things. Also, there's a difference between marketing yourself internally within your company — which you should always do — and marketing yourself externally with other developers.My second tip is to clone open-source apps. Clone something that already exists so that you stop making all these little product decisions. Maybe your implementation will be better, which is great; that's how the industry improves. And if it's worse, you start to understand the underlying trade-offs of your project. And a third one?Many people have the cold start problem when it comes to networking and content creation. Yes, you will not get much response when you start. So the way to guarantee response is what I call a "pick up what they put down" approach. If you want feedback, start giving feedback, mainly whenever people put out something new.When somebody you respect publishes a new demo, a new library, a new blog post, or a new workshop, summarize it, respond to it, react to it. Not with a YouTube reaction video, but actually respond to the meat of the content. Ask questions: Do you agree? Do you disagree? What else can you do with this implementation? Pick up on the things. Find bugs in the demos and the libraries, and you're guaranteed to get a response from that.I think that's an excellent starting point because these people are already influential. Almost definition, they have more ideas, and they know what they do. You work with them, become a collaborator. Eventually, you start to disagree with them, and you feel forced off into your own path. That's, I think, a great way to get started.
You are now working on developer experience at Temporal.io. What does it entail?Temporal is an open-source microservices orchestration system, which you could compare to Apache Airflow or AWS Step Functions. But we're better. There's a core server that is open source, and then there's all this stuff around it that needs to reach developers: documentation, developer relations, web UI, and SDKs. And I'm the head of developer experience helping each team in those areas. They are not essential to the server itself but important to how developers experience the product. I have overarching excitement in my career about helping technologies cross the chasm. I'm not sure who came up with the term, but the idea is that when you switch over from early adopters to a broad audience, there is a big gap in the middle where you have to fill in a lot of gaps with developer experience. That's what I focus on. Do you have some rituals or tools that keep you focused and goal-oriented?I try to do time blocking. For example, interview calls are on Fridays, which gives me focus on work from Mondays to Thursdays. Within the day, you have different time blocks as well. And if you can block off time for yourself too, I think you can get a lot more done.Apart from your daily job, you are a writer and speaker, and you recently published The Coding Career Handbook. What inspired you to write it?Mostly the feedback from my essay on learning in public. It was the most impactful piece of writing I've ever done; it reached over a million people. I can write about technical stuff, and I think it would be easier to sell, but React will be over someday. The thing that will not be over is career stuff, the evergreen things. When I decided to write the book, I had some time between my Netlify job and my Amazon job. So I wrote a poll, and the one with the more enthusiastic response was the career stuff. For whatever reason, this is the most valuable topic to my readers. Also, I think there's a gap in the market for leveling juniors and seniors. You can find many materials on how to learn to code and crack the coding interview. And then there's a big gap. But many people are coming into tech as juniors, and there's a lot of companies wanting to hire seniors — and nobody focuses on developing juniors into seniors.So I'm trying to contribute my thoughts as well as the thoughts of others. I collected 1,500 references to other people's ideas on becoming a senior engineer in the book. And I think if I keep at this — this is version one — I will build it up into the ultimate resource on how to become a senior engineer.
And if you were to highlight one idea from your book, which one would it be?I'd say the most underappreciated part of my book is the strategy section — the importance of picking the right thing to work on rather than just being a clean coder or choosing the right tech stack. Understanding how money is made from your software is key to selecting the right company and positioning yourself correctly within the company. You are also very active in the community: you've contributed to several other books, have a 34k+ following on Twitter, helped to run the React subreddit... How has it impacted your career?It helps you to know everybody. It allows you to understand what's going on. I'm typically the source of news to my team, and they appreciate that. Also, if you're friends with everybody, you don't have to know everything — it's all coming from that community. What open-source projects would you recommend keeping an eye on or contributing to?I left the React community because I was getting more and more interested in Svelte. I do think it is an underrated framework for front-end developers. It's not for everybody, but I think it solves a good set of problems, including state management, styling, and animation. At React, we still don't have good answers for these things after all these years.What pieces of your work are you most proud of?Mostly the community behind the coding career handbook. I set up a semi-private Discord channel for people who opt into the community, and seeing people get jobs, double their pay when they go from junior to senior — that's really exciting. It's a great place for discussion where you can be totally honest. Realizing that that's something that I can do for ten years and not get bored of it, that's something I'm proud of.

Speakers are not made — they are born out of circumstances. And Tomasz is a perfect example of a self-starter who rose to the occasion. “I started at local meetups and climbed my way up to bigger and bigger events,” he says, nodding at the fact that he's now also a seasoned instructor revolutionizing modern commerce. How did he get there?
What led you to software engineering?It's been quite a journey. Ever since I was a kid, I was interested in technology, but I was definitely not one of those five-year-old prodigies that installed Arch Linux on their fridge. I wrote my first program on a Commodore 64 copying an entire page of arcane characters from a book to a computer and hitting Enter. And then I watched the screen flash in different colors.I built — okay, copied and pasted random code till it worked, which I kind of do till this day — my first website when I was around 12, but I never thought that web development would turn out to be my career. In fact, I explicitly did not decide to pursue a Computer Science degree for various reasons. I felt I wasn't good enough and thought that programming was not for me.Instead, I decided to pursue a master's degree in Electronics and Telecommunications, which, to my surprise, was most likely harder than the CS curriculum. Along the way, I got an opportunity to learn C++, which wasn't exactly a cakewalk, but it led me to my first internship, which led to another one where I was a part of an eight-week-long paid bootcamp. There I learned web development from scratch, an opportunity I'm forever grateful for. And I've been programming for a living ever since.What is the most impactful thing you ever did to boost your career? It was back in 2017 when I decided to give public speaking a shot. Like all tech speakers, I started at local meetups and slowly but surely climbed my way up to bigger and bigger events.Contrary to a popular notion, speaking at tech conferences is not exactly something you do for money. The connections, networking, and genuine friendships that happened because of all those events are priceless, though. The doors you get to open, the places you get to see, the people you get to meet — if you're able to, I cannot recommend speaking at tech events enough.
What would be your three tips for engineers to level up their career? I wrote everything I wished I knew earlier in this blog post. In short: talk to humans rather than machines, have a deep understanding of what you are building and why, and don't be afraid to say, "I don't know." Also, learn in public, as some of my colleagues mentioned in their interviews.What are you working on right now? I'm currently a front-end engineer at Stedi, where we're building a fully serverless platform for companies to integrate and exchange business transactions with each other. Stedi is a fully remote startup with employees from all around the globe, and I'm a part of a ridiculously talented team of engineers who happen to be from the same city I'm from!The business domain we're in hasn't seen much innovation in decades, and it's such an exciting space to contribute to. We're working on challenging and complex problems. After all, revolutionizing modern commerce can't be easy. Do you have some rituals that keep you focused and goal-oriented? I'm not sure if this is a ritual, but I strive to challenge myself as often as I can and pursue new personal and professional growth areas. My favorite answer to the famous "Where do you see yourself in five years?" question is, "I don't know." I feel like if you do know where you'll end up in five years, you may not be thinking broadly enough about your potential and possibilities. In this line of work, it's crucial to be focused on growth and becoming a lifelong learner.You're an egghead.io instructor, where you've contributed with two courses and more than 170 lessons. What do you find rewarding about the experience?Joining egghead was life-changing for me. Apart from the financial incentive, having the ability to record a lesson or a course in my bedroom and teach something useful to hundreds, if not thousands of developers, is remarkable. I'm forever grateful to Joel and the entire egghead crew for having me. If you're interested, you can read a bit more about my journey with them in the post.What would you say are essential qualities and skills for teaching — and learning?Keep your eyes open as there's always more to learn. Try to learn something new every week, if not every day. When teaching, optimize for boredom. It's better to explain something again to an expert rather than to a beginner who may feel excluded.Also, when one teaches, two learn, so use teaching as a tool of solidifying your own knowledge.And don't forget to be kind. Whenever you teach someone a concept that may seem totally obvious to you because you mastered it years ago, make sure to remember that you were a beginner not so long ago too.What open-source projects would you recommend keeping an eye on or contributing to?I'm a huge fan of everything Tanner Linsley is working on, especially React Query. In my humble opinion, it's the best library since jQuery, so make sure to check it out. It's just excellent.What pieces of your work are you most proud of? Whenever someone reaches out to me saying that a video, article, podcast, or talk I created helped them, it always means the world to me. It's an incredible feeling to have something you wrote a couple of months ago reach out to someone else from across the globe and help them grow as a developer.

Developer, writer, creator, says the headline of Lee’s site, a front-end developer with 10k YouTube subscribers and 5k newsletter followers. Today an internationally recognized speaker and author of extensive courses on React and Next.js, he says he owes his success to sharing what he was learning online. "The best time to start with content creation was yesterday!" he exclaims. 
What led you to software engineering?I've always enjoyed creative work, especially building things from scratch. I have roots in design and photography, which ultimately led to a perfect match for front-end development. And how did I go from a designer to a developer? I wrote an extensive post about my journey on my blog. What is the most impactful thing you ever did to boost your career?Hands down, writing online. Sharing what I was learning online led to new connections and opportunities I couldn't have imagined. It's helped me generate passive income, land new jobs, and make some great friends. The best time to start was yesterday! And if you need a tip or two on how to kickstart your content creation, I wrote a short article that will help you make heads and tails of the whole process.What would be your three tips for engineers to level up their career?First, leave the code in a better place than you found it. Second, work on improving your written and verbal communication. And third, write documentation. You'll be the developer everyone loves. 

What are you working on right now?I'm entirely focused on leading developer relations at Vercel and Next.js but have been entertaining making another programming course as a side project. I'm also considering rebuilding my personal site — for the 10th time!Do you have some rituals that keep you focused and goal-oriented?I try to stay active, get plenty of sleep, and focus on long-term goals. It's easy to get caught up in the day-to-day, so I frequently try to think about what I want to achieve in the long run. If I'm not making progress towards a better future, then it's time to change something. As for staying focused, it's incredibly important I'm working on something I truly believe in. Otherwise, I would likely get bored very quickly. I'm bullish on Next.js, Vercel, and our mission of building a better web.Apart from your job, you also maintain a very successful content platform. Why did you start, and how did you grow it to 80k blog post views, 10k YouTube subscribers, and 5k newsletter followers?My golden rule is being helpful online. At the end of the day, if I'm consistently helping people in a positive way, all the metrics will go up and to the right over time. I started writing online about seven years ago and haven't looked back since.


You also launched two learning projects: React 2025 and Mastering Next.js. Can you tell us more about them and why you decided to provide them for free?I didn't set out to create programming courses but ultimately ended up creating the resources I wished I had earlier in my career. Most of my content creation was solving problems that "past Lee" faced. For Next.js specifically, when I started creating content, it was still relatively new and hadn't reached critical adoption. I believe that helped with the growth of my courses and audience. After some time, I ended up making both free for everyone. Money wasn't the main incentive for me, but rather helping other people — and past Lee.Are you working on a new personal project at the moment?Not now. But I'm leading a team of content creators at Vercel, so there's a lot in the works here now! My team is made up of some wonderful people, and this has been an exciting transition in my career.What open-source projects would you recommend keeping an eye on or contributing to?I've been very interested in Rust lately, with Next.js investing more into using Rust (through SWC) to optimize compiling and bundling. Check out SWC and expect more educational material on Rust in the future from our team.
What pieces of your work are you most proud of?I'm most proud of the students who have taken my courses and ultimately landed jobs or created their own products. It's very fulfilling for me and the reason I love being a content creator.***Follow Lee on Twitter

When it comes to career, Charlie has one trick: to focus. But that doesn’t mean that you shouldn’t try different things — currently a senior front-end developer at Netlify, she is also a sought-after speaker, mentor, and a machine learning trailblazer of the JavaScript universe. "Experiment with things, but build expertise in a specific area," she advises.
What led you to software engineering?My background is in digital marketing, so I started my career as a project manager in advertising agencies. After a couple of years of doing that, I realized that I wasn't learning and growing as much as I wanted to. I was interested in learning more about building websites, so I quit my job and signed up for an intensive coding boot camp called General Assembly. I absolutely loved it and started my career in tech from there.
What is the most impactful thing you ever did to boost your career?I think it might be public speaking. Going on stage to share knowledge about things I learned while building my side projects gave me the opportunity to meet a lot of people in the industry, learn a ton from watching other people's talks and, for lack of better words, build a personal brand.
What would be your three tips for engineers to level up their career?Practice your communication skills. I can't stress enough how important it is to be able to explain things in a way anyone can understand, but also communicate in a way that's inclusive and creates an environment where team members feel safe and welcome to contribute ideas, ask questions, and give feedback. In addition, build some expertise in a specific area. I'm a huge fan of learning and experimenting with lots of technologies but as you grow in your career, there comes a time where you need to pick an area to focus on to build more profound knowledge. This could be in a specific language like JavaScript or Python or in a practice like accessibility or web performance. It doesn't mean you shouldn't keep in touch with anything else that's going on in the industry, but it means that you focus on an area you want to have more expertise in. If you could be the "go-to" person for something, what would you want it to be? 
And lastly, be intentional about how you spend your time and effort. Saying yes to everything isn't always helpful if it doesn't serve your goals. No matter the job, there are always projects and tasks that will help you reach your goals and some that won't. If you can, try to focus on the tasks that will grow the skills you want to grow or help you get the next job you'd like to have.
What are you working on right now?Recently I've taken a pretty big break from side projects, but the next one I'd like to work on is a prototype of a tool that would allow hands-free coding using gaze detection. 
Do you have some rituals that keep you focused and goal-oriented?Usually, when I come up with a side project idea I'm really excited about, that excitement is enough to keep me motivated. That's why I tend to avoid spending time on things I'm not genuinely interested in. Otherwise, breaking down projects into smaller chunks allows me to fit them better in my schedule. I make sure to take enough breaks, so I maintain a certain level of energy and motivation to finish what I have in mind.
You wrote a book called Practical Machine Learning in JavaScript. What got you so excited about the connection between JavaScript and ML?The release of TensorFlow.js opened up the world of ML to frontend devs, and this is what really got me excited. I had machine learning on my list of things I wanted to learn for a few years, but I didn't start looking into it before because I knew I'd have to learn another language as well, like Python, for example. As soon as I realized it was now available in JS, that removed a big barrier and made it a lot more approachable. Considering that you can use JavaScript to build lots of different applications, including augmented reality, virtual reality, and IoT, and combine them with machine learning as well as some fun web APIs felt super exciting to me.

Where do you see the fields going together in the future, near or far? I'd love to see more AI-powered web applications in the future, especially as machine learning models get smaller and more performant. However, it seems like the adoption of ML in JS is still rather low. Considering the amount of content we post online, there could be great opportunities to build tools that assist you in writing blog posts or that can automatically edit podcasts and videos. There are lots of tasks we do that feel cumbersome that could be made a bit easier with the help of machine learning.
You are a frequent conference speaker. You have your own blog and even a newsletter. What made you start with content creation?I realized that I love learning new things because I love teaching. I think that if I kept what I know to myself, it would be pretty boring. If I'm excited about something, I want to share the knowledge I gained, and I'd like other people to feel the same excitement I feel. That's definitely what motivated me to start creating content.
How has content affected your career?I don't track any metrics on my blog or likes and follows on Twitter, so I don't know what created different opportunities. Creating content to share something you built improves the chances of people stumbling upon it and learning more about you and what you like to do, but this is not something that's guaranteed. I think over time, I accumulated enough projects, blog posts, and conference talks that some conferences now invite me, so I don't always apply anymore. I sometimes get invited on podcasts and asked if I want to create video content and things like that. Having a backlog of content helps people better understand who you are and quickly decide if you're the right person for an opportunity.What pieces of your work are you most proud of?It is probably that I've managed to develop a mindset where I set myself hard challenges on my side project, and I'm not scared to fail and push the boundaries of what I think is possible. I don't prefer a particular project, it's more around the creative thinking I've developed over the years that I believe has become a big strength of mine.***Follow Charlie on Twitter

Software engineer, lecturer, podcast host, author — is there something Emma Bostian hasn't done? She moved from America to Sweden, started working at Spotify, and took up a few challenges along the way. And now she has some career tips to share.
What led you to software engineering? I was raised in the ecosphere of tech because my dad is a software engineer at IBM, and my mom was a designer there, too. My dad always encouraged me to join STEM and take a look at computer science — however, I was convinced I wanted to be a medical doctor. In my first year of college, I declared a biology major and quickly realized I was not too fond of it. In my second semester, I switched to an actuarial science major where I took Introduction to Computer Science, and the rest is history. In my second year of college, I declared a computer science major and began my journey from there.
What is the most impactful thing you ever did to boost your career?Writing blog posts and documenting my learning journey on Twitter has far been the best career boost. I wrote purely for myself to reference the things I learned over time, and I even utilized my design skills in Figma to create custom graphics depicting difficult concepts like CSS specificity. By sharing my blogs on Twitter and engaging with the people reading them, I was able to grow an audience extremely quickly. I began receiving conference speaking opportunities, podcast requests, and course invitations to teach with LinkedIn Learning and Frontend Masters.
Ultimately, I landed my job at Spotify through Twitter, too, when a friend and follower of mine asked if I would be interested in interviewing. Now I live in Stockholm working my dream job. It still blows my mind how tweeting about my blog led me to some of the most amazing career opportunities.
What would be your three tips for engineers to level up their career? First, be patient. I often see posts on Twitter or LinkedIn about developers who were promoted to a senior position after a year. And while this is wonderful, I think we forget that each company has a different standard for what constitutes a senior developer, and everyone's journey will be different.
Second, don't be afraid to ask questions. If you try your best to solve a problem or answer a question you have, but you can't figure it out after a reasonable amount of time, ask a team member or mentor for help.
And lastly, invest in the right resources for learning. When I started my journey, I didn't know which platforms worked for me to learn. Now, I have a few trusted platforms such as Frontend Masters, Free Code Camp, or Level Up Tutorials that I go to when I need to learn a new skill.
You're currently working as a software engineer at Spotify. What does a typical day of yours look like there?I begin my day answering emails. Then we have a team breakfast and a standup remotely as we're all still remote at Spotify. After that, we might have a web tech sync with the other squads in our business unit. The day usually includes some form of pair or mob programming, depending on the work stream. 
My team always has Fika, a traditional Swedish coffee break, scheduled every afternoon. Every couple of Fridays, we have team games planned to release some stress. 
Also, I tend to have a lot of free time to focus, which is nice but makes for a boring answer to this question!
Do you have some rituals or tools that keep you focused and goal-oriented?I'll admit that I've been struggling with staying motivated in the time of remote work. I've been remote with Spotify since onboarding a year ago, but my team is wonderful, and they help me when I'm down.
Apart from that, I use Todoist to keep track of my tasks, and, naturally, I listen to Spotify while working. But other than that, not really. Maybe I should adopt some new tools to keep me on track!
My current favorite Spotify playlist is Brand New Chill: https://open.spotify.com/playlist/37i9dQZF1DX6uQnoHESB3u?si=380263b3c853442e
I also love Chillout Daily: https://open.spotify.com/playlist/7ozIozDp260fjNOZy1yzRG?si=66d6c839ec9b458a
You wrote a book called De-coding the Technical Interview. What was the impulse to do it?I wanted to give the community a manual of the essentials of computer science knowledge to ace the technical interviews. The book covers data structures like stacks, queues, or linked lists, tackles algorithms, and deals with systems design. You'll also learn about the interview process from start to finish, get tips on how to submit an amazing take-home project, or understand how to problem solve. You'll also gain knowledge on the frontend coding skills needed to excel at a frontend interview.
If you could stress one piece of advice on surviving a technical interview, which would it be?Do not lie your way through an interview. If you don't know the answer to something, just admit it. There's no shame in admitting you don't know the answer to something. There is shame in faking it and pretending like you do know the answer.
What's the single best practice everyone who writes code should follow?Remember that while you are technically writing code for computers, you're also writing it for humans. Your code should be readable and have as little complexity as possible without sacrificing accessibility or performance.
In addition to the book, you co-host the Ladybug Podcast. What inspired you to enter this field, and what are the podcast's main topics?We talk about everything tech and career on the podcast, from Java and GraphQL to how to start a business and cross-cultural communication. The podcast is a way for me and my co-hosts to share our experiences in tech, having taken different paths. And I'm really glad for doing it — it has allowed me to meet so many incredible people, learn many new things, and support my dream of teaching.
What pieces of your work are you most proud of?My technical interview book was a huge feat for me as well as my courses with LinkedIn Learning on building a tech resume. I enjoy creating things that help other people advance their careers, so I'm also proud of my courses with Frontend Masters on design systems and CSS.

Even though his bio offers quite a hefty reading, he only applied for one job in his career. The rest came along as he was building his name as a renowned speaker, teacher, and a prolific figure of the open-source community. How did Kent do it? “Commit to creating high-quality content,” he says.
What led you to programming?I had a friend when I was a teenager who was really into it, and he tried to teach me. But I just couldn't get it — it didn't make any sense to me. So I never really thought I'd get into programming, but I liked computers a lot, and I ended up going to school for electrical engineering. 
Well, that didn't work because I'm not good at math. But right when I started the program, I got a job at a company uploading videos to YouTube and that sort of thing. The work was tedious, so I decided to write a computer program to automate lots of the work I was doing with the knowledge I had about programming. And that was the first spark of things for me to use programming to solve real-world problems. 
What is the most impactful thing you ever did to boost your career? Committing to creating high-quality content. That might sound obvious because I'm a full-time educator now, but I would not have gotten my job at PayPal if I hadn't been so active with my blog. In fact, lots of my jobs came out of me being involved in the community around meetups, conferences, or open-source projects. 
How do you choose topics for the content you create, be it for your blog or podcast?I don't think too much about the content other people are creating. And I don't often consume it. My ideas come from the things that I'm working on, things that I'm learning myself, or — when I was working with a team of developers — the things that I had to remind people of in code reviews regularly. Anytime that I would have a code review comment that was pretty long to describe my position, that was an excellent opportunity for a blog post. Also, if people ask me about a topic regularly, I'll make a blog post rather than answer that question multiple times.
What would be your three tips for engineers to level up their career? The number one thing I tell people is to be a nice person. I know that sounds fluffy or silly, but it cannot be overstated. You will get so much further in your career and just in life in general if you're a nice person. That doesn't mean that you take people being jerks lying down, but how you interact with others is out of kindness. You could be the best engineer in the entire world, but if you're not a nice person, you will not reach your full potential or accomplish your goals, whatever they may be.
Second, it's just as important to decide what you are not going to learn as it is to decide what you are going to learn. You could jump into countless things — and there are successful people who are polyglot programmers, but I can't speak to that a whole lot. All I can tell you is that in my experience, focusing on specific things that I want to be truly good at has worked out great for my career. That doesn't mean that I closed myself off to other things. With my website rewrite, I have been doing a lot of dev ops-related work and a lot of back-end stuff that I've typically not been involved in. You want to keep your head up on what's going on outside of what you're doing so that you know what direction to go in when you come across problems you need to solve. However, finding a focus on what you want to be good at has helped me a lot. That way, you feel a little less stressed.
And the third one? Learn how to learn effectively. It's a three-step process: you consume, build, and teach. The consumption of newsletters and Twitter and whatever inspires you, but you don't want to spend too much time doing that — implementing it into actually building something matters. This happens naturally if you work at a company, but maybe you're not making the things you want to learn, so you may want to start a side project. The building phase is where you get experience, but you also want to solidify that experience. How? You start teaching. You don't necessarily have to teach it to people, it could be stuffed animals. The goal of the teaching is to retain in your mind what you've learned through the building process.
What are you working on right now? The big thing I'm working on right now is a rewrite of my website. It'll be much more than just a developer portfolio — I'll have user accounts, and there'll be fun things that you can do with it. And because it's more than just a website, I'm using Remix, a new cool framework in the React ecosystem. I'm also working on updating my material on TestingJavaScript.com and a TypeScript course as well. 
So, whatever I'm working on, it ends up resulting in lots of opportunities for content.
Do you have some rituals that keep you focused and goal-oriented? I have a notepad where I keep all of my notes of what I'm going to do for the day so that when I'm checking things off, I'm not distracted notifications. I've tried apps for that, and that does not work well for me. 
I also am a firm believer in inbox zero. I have my work inbox and my personal inbox, and I keep them both at zero. And I kind of use that as a to-do list. 
And if I'm not feeling excited about working for some reason, I will often hop on my Onewheel, which is an electric skateboard that only has one giant wheel in the middle. It's just a total blast, and I'll hop on that with my backpack and a charger, and I'll go to a Starbucks or a park just to declutter my mind.
What things in the React universe are you excited about right now?React version 18 is coming out soon. The experimental version is out there, and it's fun to play with. I'm just really thrilled that it's no longer a concurrent mode but concurrent features that you can opt into. Cool things like that will enable React server components in the future. 
But the biggest thing I'm excited about is Remix. That's huge. It eliminates a lot of problems that are solved well other tools, but when I'm using Remix, I don't have those problems, so I don't need those clusters.
You already said that teaching is an integral part of the learning process, and you stand your word since you're also a full-time educator. What inspired you to enter this field?I have been a teacher for as long as I can remember. I grew up in a church where you talk in front of your peers from a very young age, and my mom was an elementary school teacher, so teaching has just always been a part of me. 
I really just enjoy sharing what I'm learning with others. As far as teaching technical topics, I gave my first workshop when I was still a student at Brigham Young University. With my fellow, we taught how to use AngularJS, and I got Firebase to sponsor pizza so they would show up, and that was pretty fun.
Then I started teaching on the side at egghead.io right after I'd graduated. That was when I first got a paycheck for teaching. And I realized that teaching could be quite lucrative and support my family and me as a full-time endeavor. So I did it — I quit my job. I'm a very risk-averse person, so I'd done teaching as a side hustle for four years just to verify that I could make this work.
When TestingJavaScript was released, and I got that paycheck, I realized that I didn't need my PayPal salary anymore. I could just focus my daytime on teaching and give my evenings back to my family, which was a nice trait.
Apart from that, how has teaching impacted your career? Earlier I mentioned that pretty much all of my jobs came because I was perceived as an expert. After the first job, where I was an intern and then converted into full-time, I never applied to another. I worked for four different companies, and they wouldn't have recruited me if they didn't know who I was and what I was doing. My content is how they knew who I was — I just made it easy for them to find me. Teaching made that impact. It made my career. 
We talked about React and Remix. Are there any other open-source projects that you'd recommend keeping an eye on or contributing to?I have some myself. React Testing Library is probably the biggest one that people are familiar with. And if React isn't your jam, then other framework versions of the testing library. 
React Query is also really popular. If you're using Remix, you don't need it, but if you're not, I strongly advise using React Query cause it's a stellar, fantastic library, and Tanner Linsley, the creator, is a stellar and fantastic person. 
What pieces of your work are you most proud of? Probably the biggest thing I've ever done is EpicReact.Dev. It has helped tens of thousands of people get really good at React, improve their careers and make the world a better place with the skills that they develop. My whole mission is to make the world a better place through quality software, and I feel like I've done that best with Epic React. 
There are things that I've built at other companies that are still in use, and I'm proud of those cause they've stood the test of time, at least these last few years. But of everything, I think Epic React has made the biggest impact.

He turned a successful blog into a thriving YouTube channel, a newsletter with thousands of subscribers, and a great online presence. “I owe a significant part of my career to content creation and social media,” says Catalin Pit in his interview with GitNation.

What led you to software engineering?
I started accident, actually. I was studying accountancy, preparing myself to become an accountant. However, before finishing school, I moved to the UK, and things changed. I went to a college where I had to choose between a handful of subjects — and IT was the most familiar and attractive of all of them. After three years in college, I was so excited about programming that I went on to study computer science at a university. So yes, I got into software engineering mistake, but I'm more than happy with how things turned out.
What is the most impactful thing you ever did to boost your career?
Starting a blog and taking social media presence seriously. For real, I wouldn't have my current job at Hashnode if I hadn't stepped up my game in that department.
What would be your three tips for engineers to level up their career? 
First, don't be afraid to ask questions. Second, go out and broaden your network — meet people and build genuine connections. And finally, create content. By doing so, you'll help not just yourself but others as well to advance in the given field or profession.
And if I may add one engineering advice, I'd say don't try to write fancy-schmancy code. If you can, use the KISS principle: "Keep it simple, stupid." Obviously, do so without sacrificing readability and performance.

Do you have some rituals that keep you focused and goal-oriented? 
Actually, I just sit down and work! I don't even listen to music. I tried listening to lo-fi songs when working, but they still distracted me...
I've been working from home over the last year and a half, and the place where I go to relax and recharge is the gym. I try to go there once I finish my work, and when I return, I tend to work two or three hours on my stuff, be it my blog or my YouTube channel.
But, sometimes I skip that. Life's not all about work, and I try to keep a healthy work-life balance. It's easy to get overworked when you work remotely, and you constantly face issues such as poor time management and no face-to-face interactions. To avoid feeling down, I stop checking all work-related stuff when I'm done for the day, and I change my workplace — sometimes I go to a café just to be surrendered people. In addition, I work without checking my phone, notifications, and inbox for a specific timeframe to avoid distractions. And to manage my time, I use the Pomodoro technique.
As you mention, you have a blog, a YouTube channel, and even a newsletter. What made you start with content creation? 
I began after getting my university degree. First, I launched the blog, and I did to reinforce what I'd learned. To teach is to learn twice, as they say. By explaining things and going over them, you get to understand the subject at hand better. I was studying data structures and algorithms to apply for jobs, and each time I'd learn something new or solve a problem, I'd blog about it. I kept doing it, and it became a habit. Now, I don't think I will ever stop writing programming articles.

Do you cover different topics via different media?
I prefer to create a piece of content and distribute it through all the channels. For instance, a blog article can serve as a script for my YouTube video. It makes the whole process more straightforward, and your audience can choose the content format they prefer.
How has content creation impacted your career?
It's been crucial to my professional development. As I said earlier, I got my current job thanks to producing content for the community, and I constantly get various job offers, side gigs, and other proposals because of my blog entries or YouTube videos. 
What pieces of work are you most proud of?
I don't want to get carried away, but the truth is that content creation changed my life for the better. So I'll say I'm really proud of my blog. It gave me many opportunities I did not expect, and it helped other people skill up. That's just great.
