About
Generalist, by design.
I'm a full-stack developer who cares as much about clean systems as about the feel of a button. I work across the stack so the seam between product, design, and engineering disappears.
Lately I've been building on the modern edge stack: TypeScript, React Router, Cloudflare Workers, and Postgres. I'm happiest when a small team needs a generalist who can move from schema to ship.
