role fit
where I plug in — the four shapes of work I do.
02 — role
Software Engineer
End-to-end product builds: system design, typed contracts, type-safe TypeScript and Python, sensible test surface, observability hooks. The kind of code that survives past the prototype.
03 — role
Backend / API
FastAPI and Node services with auth (JWT / OAuth / HMAC), background jobs, webhooks, queues, and storage layers across PostgreSQL, MongoDB, Neon, R2. Cloud Run / Docker / GCP for the runtime.
04 — role
Full-stack AI products
Next.js interfaces sitting on top of FastAPI + LLMs — real shipped surfaces that clients use. Approval queues, audit trails, role-gated admin, replayable run state. Production, not demo.
