Most of my side projects start with a very specific annoyance:
- a prediction game I was losing;
- a recurring coffee chat that kept matching the same people;
- ranked matches made worse by bad bans;
- a ferry I did not want to miss.
So I built tools for them.
I like software that is small enough to understand, useful enough to keep using, and honest about what it cannot know.
Coffee Roulette Deterministic fair matching with joint BYE selection, repeat avoidance and transactional history. |
World Cup Prediction-Game Model Elo, Poisson goals, market odds and pool-point optimization. |
DraftLab A CLI for better bans and picks in Brawl Stars Ranked. |
Kiel Ferry Clock Live departures and leave-home reminders on a Raspberry Pi display. |
real problem → simple model → test it → use it → improve what is wrong
I mostly work with Python, Node.js, C++, Raspberry Pi and whatever else is appropriate for the problem. I care about clear documentation, reproducible results and graceful handling of imperfect data.
Current recurring rabbit holes: industrial automation, energy systems, football models, practical tools and making small physical things a little smarter.
