About Me

I'm a full-stack software engineer with over 12 years of professional experience building everything from interactive web apps to hardware-driven IoT projects. I'm equally comfortable diving into a React component tree, designing a REST API, or soldering an Arduino circuit.

When I'm not shipping code, you'll find me crafting in my workshop, tinkering with Linux, or gaming.
