I build web and mobile applications across the full stack—React, TypeScript, Swift, Node.js, Python, Go.

Most recently at Sovrn, I led the modernization of a legacy JavaScript ecosystem into a TypeScript monorepo, shipped an AI support platform that cut ticket volume 60%, and built an iOS app from scratch that generated new revenue.

I care about code that's maintainable, systems that scale, and products that ship.
