About Me

Turning ideas into
digital reality

I'm a full-stack developer with 5+ years of experience building web applications. I specialize in React, Node.js, and cloud infrastructure. I love clean code, open-source collaboration, and solving challenging problems.

When I'm not coding I'm either reading about distributed systems, contributing to open source, or hiking somewhere remote with no Wi-Fi.
