I build AI, robotics, hardware, and physical-world systems.

This channel documents my work across embedded AI, PCB design, firmware, robotics, computer vision, mechanical prototyping, fabrication, medical-device engineering, and field-tested hardware.

I’m Devin Willis — founder-engineer, CTO of PromptPCB, and Director of Engineering at Golden Hour Medical. My work lives where software, hardware, AI, and messy real-world constraints collide.

Expect build logs, debugging sessions, prototype breakdowns, AI/robotics experiments, fabrication notes, and lessons learned from systems that actually have to work.

No fake founder theater. Just building.
