About

I’m a software dev and systems architect who loves messing around with hardware. I help businesses design, launch, and keep their systems running smoothly, always aiming for practical, smart solutions that actually make sense. In my free time, I build micro drones from the ground up (handling the PCB layout, soldering, coding, and inevitable crash tests). Outside of tech, you'll find me playing video or board games, or brewing a fresh batch of homebrew beer.

Killing the Spider: Drone Gets Its First PCB

I had firmware that worked and a prototype that didn't, so I designed my first custom PCB.

The GPL Trap: Why I Rewrote My Entire Flight Firmware from Scratch

I spent weeks rewriting flight firmware from scratch just to avoid a licensing trap, only to realize I was flying blind. This is the story of how I built a custom 'Mission Control' to see the data.
