Profile

Connections

I'm a full stack developer with a deep love for well-architected systems and intuitive user experiences. I specialize in the React ecosystem and Node.js backends, always exploring new ways to make the web faster and more accessible.

When I'm not coding you'll find me contributing to open source, writing about software development, or brewing my fourth coffee while reading about distributed systems.
