We build platforms in perfect environments, but the real world is anything but that.Real teams need to move fast, stay pragmatic, and make difficult architectural choices, each with their own trade-offs. So how do we keep UX, resilience, and performance at the forefront while the architecture underneath them continues to evolve?This talk looks at web experiences as a full-stack problem. From the backend, through APIs, and infrastructure, all the way to the frontend, we'll explore how each layer shapes the experience we ultimately deliver to the user.Through a real-world architecture case study and increasingly hostile conditions, we'll look at how caching, data fetching, streaming, payload design, and resilience strategies can evolve together, and how to navigate the entire stack to build experiences that stay fast and reliable at scale.

Built for Turbulence: Architecting Full-Stack Web Experiences That Hold Up in Any Environment

It’s entirely possible to be a strong frontend engineer while remaining mostly oblivious to availability, SLAs, SLOs, and delivery metrics. Many teams are structured that way, and it works, until you want to increase your impact beyond the UI. This talk is about expanding the frontend perspective to include the system it lives in. Not to turn frontend engineers into SREs or platform specialists, but to build full-stack awareness that leads to better decisions, safer changes, and healthier delivery practices. We’ll look at resilience as a mindset across the software development lifecycle, and how practices like atomic changes, trunk-based development, feature flags, and automated rollbacks directly affect frontend work, even when the failures don’t originate in the UI. We’ll also connect these practices to availability targets, SLOs, and DORA metrics, and explain why failure tolerance is contextual, from highly regulated systems with near-zero tolerance to products where controlled failure is acceptable. The goal is to help frontend engineers understand how their work fits into the larger system, so they can ship faster, reduce risk, and increase their impact within a team without losing focus on frontend excellence.

What happens when 'just integrate Stripe/Adyen/Revolut' isn't enough? As platforms grow, payments turn from a simple integration into a complex web of gateways, compliance, and strategy conflicts. This talk is for anyone who's hit scaling pain. I'll walk through the hard lessons from moving millions through fragmented systems, and show how treating payments as orchestration, not a feature, can unlock real growth. No fluff, just the realities of building monetization systems that scale.

What do you do when your product’s performance crumbles, but the APIs you work with are out of your control?This was the reality we faced while building a fintech payments dashboard. Massive payloads, strict compliance, and scattered APIs were slowing merchants down and wrecking workflows.In this talk, I’ll walk through our real-world quest to rescue the user experience by leaning on full-stack frameworks like NextJS, and others that let you design effective API handlers and proxies. You’ll see how we profiled true bottlenecks, built a Backend-for-Frontend layer to reshape data, balanced API criticality across the stack, applied caching and resilience architectural strategies.We’ll also look at the infrastructure side: how to use FaaS/IaaS to manage network constraints, reduce payload impact, and improve reliability without changing the source APIs.Expect live demos, battle-tested patterns, and hard-earned lessons for building resilient, user-centric apps, front to back, even when the odds aren't on your side.
