About

I'm a frontend/full-stack engineer with senior and management experience building web products. I care about pragmatic execution — shipping the right scope, with good UX, on a stack that stays maintainable as it grows.

I've taken products from first prototype to production, led and mentored engineers, and focused on the details that make web apps fast, accessible, and reliable.
