A frontend engineer who ships at scale
I'm a frontend developer with 8 years building and scaling high-performance web and mobile apps — most of it in the React ecosystem (React, Next.js, React Native), with growing backend range in Node.js and SQL. Along the way I've shipped custom CMS platforms, wired in complex analytics, and learned to care as much about the design system underneath as the interface on top.
