BatRX.

I designed the learning systems for BatRX, a batting technology that helps professional baseball players choose the right bat. Players and instructors get measured feedback on every swing, so bat decisions come from data.

Much of the work was understanding how players and instructors actually interact, and deciding which measurements and body motions had to be captured to analyze a swing and the moment of contact. From that I built a simple pipeline for adding player profiles, player information and batting data, and for turning it into performance information players can review later.

After a session, players see real-time feedback and can open detailed metrics and comparisons for future reference. Professional baseball players use it today, and it is making a difference in the game.
