Juegalo — Predictor

Predictor was a sports-prediction game: players called outcomes ahead of real fixtures and were scored against what actually happened. I built it and the partner-programme site alongside it.

The interesting constraint was live sport. Fixtures move, matches get abandoned, results get corrected hours later — and every one of those events has to resolve fairly for people who already committed a prediction. Handling that without either freezing the game or quietly changing someone's result was most of the work.

It settled at 500–1,500 daily active players before being discontinued.

Employer work, so there is no code to show and nothing here about its internals.
