Sport & Engineering
Fifteen years of training.
Seven years of building.
One blog where both finally make sense together.
Written by a former national-team sprinter who now builds sport-tech hardware and thinks about which problems are worth solving, for anyone who trains seriously, builds things, or is curious about where sport and technology meet.
What you will find here
Four areas. One perspective.
Training theory, stripped bare
How the body adapts, how to structure training intelligently, and how to navigate a field full of contradictory information. No ideology. Just what works and why.
How things work, without the equations
Sensors, microcontrollers, protocols, computer vision. Complex concepts explained with intuition first and maths never.
Where sport meets a soldering iron
Real projects built at the intersection of sports science and engineering. What drove the idea, what broke, and what I would do differently.
Beyond the build: what to build, why, and how it scales
Technology strategy, product thinking, and the decisions that separate a working prototype from a product people can trust.

Build vs. Buy: Why I Open-Sourced Part of ODKI Instead of Protecting It
The ODKI sensor was never a secret worth protecting. The real decision was about what to open, what to keep closed, and why interoperability turned out to be the actual business strategy.

IMU Sensors in Sport: Why Understanding Quaternions Is Non-Negotiable
When a barbell rotates, its IMU sensor stops measuring the right axis. Quaternions and the Madgwick filter fix this — here is how they work and why every sport sensor needs them.
