Full-stack tool that converts golf swing video into biomechanics feedback (X-factor, spine tilt, shoulder/hip turn) using MediaPipe pose extraction and a custom-trained YOLOv8 detector (88.9% [email protected] on 11.5K labeled instances).

ATP-style match stats from a single rear-fence camera — YOLOv8 ball/player tracking, MediaPipe stroke classification (87% accuracy on 1,400 labeled strokes), and OpenCV court detection, surfaced through a React/Recharts dashboard.

Practice/race pacing-light system for Duke's D1 track & field team — 24,000 addressable LEDs across a 400m track, a C++ engine with sub-100ms timing precision, and a 24V power layout, at 89% lower cost than commercial systems.
