How I Work
Backend development requires clear thinking about system boundaries and responsibilities. My approach prioritizes clarity and predictability.
- API-first design: The frontend is just another API consumer. This ensures consistency and reusability.
- Clear ownership: Each service knows its responsibilities. No ambiguity about where logic belongs.
- Boring is good: Proven patterns over clever solutions. The 3am debugging session will thank you.
- Documentation as code: API specs, database schemas, and system flows documented where developers look for them.
