Scaling Fast – Engineering Lessons From ~15 Years of Tech Startups

Today's Talk focused on code architecture, modularization, and scaling in software development. The speaker discussed the benefits of separating code by domain and using tools like NX to improve productivity and enforce modular architecture. They also highlighted the importance of automating library creation and configuration. Additionally, the Talk covered code scaling and deployment strategies, including caching and automated code migrations. The speaker emphasized the flexibility and scalability of Fastify and the advantages of using a monorepo for front-end and back-end development.

This Talk discusses automating code changes for Android repositories, utilizing tools like JSCodeShift and Abstract Syntax Tree. The speaker shares a real use case example of maintaining a design system library and making changes to a component. The talk emphasizes the importance of automating repetitive tasks and using the power of abstract syntax tree for code changes. The Q&A session covers topics like source code formatting, TypeScript support, and cultural embedding of code mods. The talk concludes with insights on when automation is worth it and the limitations of code mods for monorepo changes.

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.
