Project Yoked

An all-in-one fitness platform: workout tracking, a short-form video feed, nutrition, per-muscle recovery modeling against an anatomical diagram, AI coaching, an Apple Watch app and a trail mapping system. I was co-founder and CTO and built the stack. It's shut down now. The marketing site still loads, the platform behind it doesn't.

Project Yoked was meant to replace half a dozen fitness subscriptions with one app. A workout library and tracker, a reels feed, social, gamification, analytics, nutrition, and a Recovery Engine that modeled fatigue per muscle group against an interactive anatomical diagram. On top of that an Apple Watch app, home-screen widgets, Quick Actions, and near the end a whole trails system running self-hosted Nominatim for geocoding.

I owned the stack. FastAPI backend, React on the web, React Native on mobile, plus the architecture, the infrastructure and the deploys.

It's shut down and I'm not going to dress that up. It was too much surface area for the team behind it. The marketing site still loads because it was served off the same backend, so you can go and look, but nothing behind it works and the signup buttons go nowhere.

I could turn it back on. Almost everything I do well now I learned building this, and two libraries fell out of it and outlived it: YokedCache, which I still use every day, and the Expo Media Engine.
