A. Sabit Ariff

Engineer and athlete from Ghana, West Africa.

I have a BSc in Electrical and Electronics Engineering and a background in Computer Science research, robotics and mechatronics. Right now I'm teaching myself Applied Mathematics and Computational Science and Engineering — the intersection of rigorous math, physical modelling, and software that I find most interesting.

I build things at the edge of sport, science, and code. My main project right now is SprintLab — a free, open-source kinematic analysis tool for sprinters. You upload a video, it runs research-level pose estimation (133-keypoint whole-body tracking via RTMLib), and returns ground contact times, joint angles, angular velocities, center-of-mass trajectory, and more — all in real units once you calibrate a reference distance. No lab required.

SprintLab exists because biomechanics labs and sports science infrastructure are essentially nonexistent where I'm from. I built the tool I wished I had, and made it open so anyone, anywhere can use it.


Currently working with

Languages — TypeScript · Python · (learning) C++ Frontend — React · Vite · TailwindCSS · Radix UI Backend — FastAPI, etc Math / Science — Linear algebra · Calculus · Numerical methods · Signal processing


Interests

  • Computational biomechanics and motion analysis
  • Applied mathematics and numerical computing
  • Building tools that lower barriers for athletes and researchers in under-resourced regions
  • The physics of human movement
  • Lots of other stuff

"I looked around for a tool to help level the playing field — and realized I had to build it myself."
