About

I’m a full-stack developer based in Montreal with 8+ years of experience building web products across SaaS, high-traffic applications and performance-constrained platforms.

I mostly work with TypeScript, React and Node.js and enjoy solving problems that sit between product, frontend, backend and browser capabilities.

Outside software, I’m usually playing football, travelling, playing guitar or trying to sing reasonably in tune.
