About

I turn fuzzy ideas into products that ship.

I'm a full-stack developer who cares as much about the last 10% of polish as the architecture underneath it. Most of what I build starts as a small annoyance in my own day — then becomes a tool other people end up relying on.

I work primarily across the MERN stack, but I'm happy anywhere the problem takes me — a browser extension, a Laravel blog, a zero-backend utility that runs entirely on the client. What stays constant is a bias toward simple, fast, and private.

Today my projects quietly serve thousands of people a month, from content creators to fellow developers — and I'm always looking for the next real problem worth solving.
