Live, love, bike, and code.

I build tiny tools that remove friction for developers, creators, and everyday workflows - from client-side converters to Copilot-powered CLIs, polished diagram editors, and playful utilities for macOS, Windows, and Nintendo Switch fans. My focus is simple: make small things that feel good to use.
