Fantasy Football Draft Helper(opens the GitHub repository)

Multi-user live draft platform for auction, snake, and hybrid formats. Projected prices come from a comparable-player model trained on seven seasons of the league's own auction history, backed by a deterministic mock-draft engine, PocketBase realtime rooms, and API-rule authorization. Built and maintained through agentic development — architecture decision log, agent guardrails, and a backtested value model included.
