Hey, we'll discuss scaling fast and engineering lessons learned in the last 15 years of tech startups. Scaling involves three things: business, team, and tech. Business scalability relies on sales and customer acquisition costs. Engineering is a tool the business uses. Scaling the team is vital as tech problems are often people problems. Team structure affects architecture and product development process. Organize teams based on purpose, not technology. Spend less time being blocked by other teams. Ship features without getting blocked. Own your own mess. Focus on product engineering partnership. Build faster using feedback cycles. Build appropriate solutions for your use case. Let go of ego and experiment with different approaches. Engineers own their own mess. Avoid work in progress. Finish the work and focus on fixing it later. Have a conversation before writing code. Scaling the tech is easier than you think. Pick an off the shelf design. Save innovation for core parts. Pick existing solutions. Focus on solving the problem. Don't waste time trying to predict future scale. Scale will surprise you. Do what works for your business. Push back on unnecessary complexity. Understand the cost of ideas. Modify the situation to fit existing design. Architecture is like a dependency graph on your code. Reduce architectural complexity by organizing code based on what it does. Use vertical models and avoid creating excessive dependencies. On the client, use vertical modules. On the back end, consider a service-oriented architecture. Start with a monolith and transition to microservices if necessary. Use folders instead of microservices when you have a small team. Use vertical models and contract or type-driven development to define clear APIs and interfaces. Avoid highly interconnected code and duplication. Focus on data structures to avoid complexity and the need for translation layers. Building translation layers can lead to slow user experience. Vertical teams aligned with vertical code allow for fast problem-solving, full control of features, and efficient data handling. Understanding the entire domain enables faster development with fewer bugs.

Building a business is a slugfest to see who gets more customers first. You have to adopt that mindset when writing code. As an old boss told me once: Clean code won't matter if we're dead. You have to shift your mindset from best practices to getting shit done. But you can't go too wild or the tech debt will kill ya.

This Talk discusses the story of continuous improvement in software development. It emphasizes the importance of measuring software delivery performance using metrics such as lead time, deployment frequency, change fail rate, and time to restore. Code reviews play a significant role in improving software delivery, and exploring the potential impact of AI on code reviews is recommended. Focusing on documentation and proper utilization of the cloud can improve organizational performance. Finally, a good culture, user focus, and collaborative platform team are crucial for success in software development.

For nearly a decade, the DevOps Research and Assessment (DORA) project has studied the behaviors of thousands of software development teams and discovered the key capabilities that reliably predict success. DORA has consistently found that not only do top performers lead their industries in both release velocity and service reliability, they achieve better business outcomes and have more satisfied employees.In this session, we’ll unpack the research findings and outline key steps your team can take toward continuous improvement.We will couple these findings with stories "from the field" about how teams are putting these ideas into practice.

The Talk discusses the code review process and the importance of software quality. It emphasizes the need for maintainability in code and the use of guidelines tailored to the team. The Talk also highlights the significance of functional suitability and the challenges of code review. Automation and documentation are recommended to improve code reviews and ensure software quality.

It is very common for teams to have code review processes and this usually happens through pull requests. Each comment represents a step towards improving the quality of the software, however, there is a wide variety of points of view. The seniority of the team, the team itself, the company, the time left, the mentality, internal agreements, all of this impacts the way of reviewing code. As a tester, I need to understand what happens in the code and when reviewing it, to identify flaws in the development process and improve my testing strategy. In this talk, I will bring the results of research I carried out analyzing the comments contained in pull requests from the 10 most popular GitHub projects created in Javascript and bring some insights related to what I discovered. Among them: are which software quality characteristics are most exercised by Devs, which are weak points in their development process, where we can improve our tests to anticipate failures, and tools that can be used to test more comprehensively, among others.

This Talk discusses the journey from thousands of Lint failures to zero in a codebase at Linton that is over 80 years old. The approach involved implementing rules, incentives, and tooling to address the issue. The tool called Checkup was used to visualize ESLint failures by team and lint rule, providing accountability and responsibility. The efforts resulted in cleaning up over 6,000 lint failures, with 55 contributors, and a 30% increase in perceived code quality.

Lint rules enable us to uphold code quality and minimize errors. It can positively impact developer productivity and happiness especially when working in a massive application with multiple teams working together. But what if your large scale application contains thousands of lint failures over the many years it has been running in production? This talk will explore actionable strategies for effectively addressing lint failures at scale so that we can once again rely on lint rules to ensure consistent code quality and streamline development processes, leading to a more robust and maintainable codebase.

Welcome to my talk on using gamification to improve quality. Code quality is crucial and involves maintaining technical debt, ensuring maintainability, and prioritizing delivery and quality. To improve code quality, create a new standard, automate enforcement, and motivate teams. Resolving merge conflicts by removing warnings and automating warning decrease and error reduction can prevent future issues. Strive for zero errors by finding a balance, enhancing tools, blocking pull requests with errors, and incentivizing developers.

Building software is all about hitting the right spot between features and quality. But we rarely talk about how to measure quality. Let’s look at how a gamification system (points &amp; leaderboard) within a GitHub action helped developers on my team care about quality!
