I build software around movement.

I'm an ML engineer in Denver. I run and swim, and most of what I build comes from that: a gait-analysis iPhone app with a GPU cloud pipeline (Run Fun), a swim recorder built on Apple Watch sensors, a way to steer software using body motion alone, and an RC truck that taught itself to drive down a trail using nothing but a phone camera.

My robot drove itself down a trail. Then it met a corner.

The Robo Bump Truck: an RC truck carrying a Jetson and an iPhone, where the phone's expensive sensors generate the training labels and the model that actually drives sees nothing but camera pixels. Straights solved. Corners not, and why I couldn't fix them is the more useful half.

I built motion controls across three Apple devices at once. Most of it worked, some of it didn't, and the reasons why are useful if you're building anything motion-controlled. Video inside.

Shipped: Run Fun, gait analysis and voice coaching for runners, on the App Store.

I do some consulting in motion sensing, computer vision, and applied ML. If you have a project, email me: [email protected]
