AI Product Engineer — Event Card 72h Performance

You build the leaderboard end to end, from the backend that computes each card's basket return over the fixed 72-hour window to the frontend that ranks and displays it. You keep the rankings live over real-time data feeds and expose them so AI agents can read the leaderboard programmatically.
