Kevin Tellez, 13 years turning complex problems into clean interfaces.

01About

I'm a full-stack developer with 13+ years of experience building products with Angular, React and Node.js. I enjoy the tricky parts: untangling complex features, hunting down bugs, refining codebases, and helping junior developers grow.

Outside of code, you'll find me mountain biking, playing soccer, or walking my dog Jack. 🐶
