About

I'm a Full Stack Engineer who loves building things that feel fast and work well. Real-time systems, developer tools, data-heavy apps — if it's complex under the hood but simple on the surface, I'm into it.

Outside work, I build side projects — game trackers, npm packages, desktop apps — either to solve a problem I'm facing or because an idea felt too cool not to build.
