Senior full-stack engineer. For nearly two years the sole engineer on a music discovery platform in production beta, covering the FastAPI backend, the React and TypeScript front end, Stripe billing, a partner API, production readiness and the Linux servers it runs on. I have also shipped LLM products, including a voice assistant suite with structured-output tool routing and a retrieval-based travel assistant over a dataset I collected first. In 2022 I built a weather graphics system that still runs unattended at nrvweather.com. Five years of contract work, Top Rated Plus on Upwork with 100% Job Success across 39 contracts.
