I will build a custom pose estimation and motion tracking system


About this gig
I build custom AI systems that track human body movement from video or webcam feed from simple 2D joint detection to full 3D pose reconstruction.
Whether you need real-time rep counting for a fitness app, motion analysis for sports/physiotherapy, or skeleton tracking for a dance/animation tool, I design and deliver a working pipeline tailored to your use case.
What I can build for you:
- Real-time 2D pose/joint detection (webcam or video input)
- 3D pose estimation from 2D keypoints (lifting 2D to 3D space)
- Automatic rep counting and form-checking (e.g. squats, curls, push-ups) using joint-angle thresholds
- Custom motion metrics (range of motion, symmetry, joint angles) for physiotherapy or sports use cases
- Web-deployable pipeline (API + simple frontend) so you can plug it into your product
Why work with me:
I've built and deployed a full 2D-to-3D pose estimation system end-to-end from a custom-trained deep learning model (evaluated at ~50mm average joint error, 95%+ accuracy within a usable threshold) to a live web app with real-time 3D skeleton visualization and an AI-powered gym rep counter. I'm not just wiring together an off-the-shelf library I understand and can customize the unde

FAQ
Do I need to provide a dataset?
No, for most use cases (rep counting, basic tracking) I can use pretrained detection models. If you need a custom-trained model for a specific domain, that's available as a custom offer.
Can this run in real-time on a webcam?
Yes, real-time webcam tracking is supported for the 2D pipeline. 3D lifting can also run near real-time depending on your latency requirements let's discuss your specific use case.
What tech do you use?
MediaPipe for 2D keypoint detection, PyTorch for the 3D lifting model, FastAPI for backend/API deployment, and React/Next.js if a frontend is needed.
Can you customize this for [my specific sport/exercise/use case]?
Yes, message me with details before ordering so I can scope it correctly (this affects which package fits and delivery time).
