Our Engineering Principles

1. Type Safety First : Leverage TypeScript to catch bugs at compile time not production

2. Server Components by Default : Use React Server Components for optimal performance client components only when needed

3. Progressive Enhancement : Build features that work without JavaScript then enhance

4. Accessibility Matters : Every component should be keyboard-navigable and screen-reader friendly

5. Trunk-Based Development : Small frequent commits with feature flags over long-lived branches

6. Documentation as Code : Self-documenting code with helpful comments where complexity is unavoidable

7. Observability Built-In : Every feature ships with error tracking performance monitoring and analytics
