About

Senior Front End Engineer with 15+ years building and shipping consumer-facing applications at scale. From award-winning streaming platforms serving 130M+ subscribers (Warner Bros. Discovery) to modern headless commerce ecosystems built on Medusa.js, Next.js, and TypeScript. Expert in React, cross-platform development, and accessible, performant UI across web, mobile, and TV.

I'm currently creating a multi-vendor vehicle marketplace and a specialty coffee e-commerce platform; both built from the ground up with Medusa.js v2, Next.js, and TypeScript. I care about clean architecture, thoughtful UX, and code that ships.
