01 / ABOUT

I got into development at 14, self-taught during the pandemic — starting with C# and .NET through YouTube courses, then picking up Python, Go, and Next.js.

These days I build full-stack web apps, hardware projects, and design work on the side — while working toward a BS in Computer Science.

A tech advocate and enthusiast at heart — I love coding, breaking things apart to see how they work, and turning ideas into things people can actually use.
