I build robots, design electronics, and write code. I served as the electrical lead for FRC team 1771, and my projects have ranged from small robots to a warehouse automation system.

Rubber Duck Robotics is my combat robotics project. I design, build, and drive Bubbles, then bring it back to the bench to figure out what to change before the next event. I enjoy the whole process—CAD, electronics, programming, and finding out why something didn’t work.

05 / Support the builds

BACK THENEXT BUILD.

Want to help me keep building and competing? I’m looking for support with parts, repairs, and competition costs.

Whether you're an individual or a business, I'd love to hear from you. Sponsors can get featured in build videos and competition coverage, and we can work out the details together.
