Sunday Sense
An interactive NFL prediction app that turns a football opinion into a prediction you can revisit.
The idea
How can fans test which matchup factors they value and learn from the result? Users choose a game, adjust the importance of football factors, and save their pick before kickoff.
What I built
A web app connecting team statistics, adjustable factor weights, saved predictions, and postgame feedback. Pregame snapshots preserve the information behind a pick so users can review it after the game.
I validated the baseline model with a walk-forward backtest: 766 games from 2022–2024 for training and a 255-game 2025 holdout. The market-only model achieved 64.3% accuracy with a Brier score of 0.2137, outperforming blends with ESPN's predictor. Full methodology and limitations are documented in the app itself.
A personal project for exploring predictions and learning from results. It's educational, not betting advice.
