The shape of
my work.
I care about clean architecture (Hexagonal, DDD, Screaming), performance (SSR/SSG, caching, query tuning), and teaching — writing, code review, and pairing with anyone willing to push past their comfort zone.
Comfortable across the stack — frontend, backend, data, infra. Allergic to shortcuts.
