Work with me

I'm Colin Rooney — ML engineer in Denver, founder of ROONEY Tech. For the last 18 months I've been building Run Fun, a gait-analysis iOS app: on-device pose estimation, cloud GPU video rendering, a voice AI coach, and an Apple Watch companion. The posts on this site come from that work.

I consult in the areas the site is written from:

• Agent-assisted development workflows — making coding agents reliable on high-stakes, multi-step work: runbooks, independent verification, headless CI/CD and App Store pipelines.
• iOS + wearable sensor products — camera/IMU capture, on-device ML, watchOS, and the cloud GPU pipelines behind them.
• Applied ML for movement and video — pose estimation, gait analysis, video processing at consumer-product cost points.

The posts here are the portfolio: real problems, verified fixes, receipts.
