Engineering philosophy

How I build software

Principles sharpened over five years of shipping high-traffic interfaces into production.

Maintainable architecture

Clear module boundaries, predictable state machines and typed contracts that a team can scale without fear.

Type safety & APIsTS + Zod

Measured performance

Core Web Vitals and real-user monitoring drive the architecture. LCP, INP and CLS are verified before anything ships.
