01

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.

Parlay Party(opens the GitHub repository)

Collaborative NFL player prop rooms where friends on separate phones each add legs to one shared slip, then send the finished parlay to whichever sportsbook pays best. Live odds flow through a normalized provider adapter with server-side key handling, response caching, and a monthly request budget guard, while a rules engine blocks duplicate and conflicting legs before the host locks the slip.

Automated weekday pipeline that converts TLDR Tech newsletters and linked source articles into two-host MP3 briefings. Removes sponsors, handles extraction fallbacks, validates generated dialogue and audio, then delivers episodes through private R2/RSS feeds or email.
