NFL Fantasy Agent
Team lead, two-person team
A multi-agent assistant that answers fantasy football lineup and waiver questions. Every verdict is grounded in SQL results, and a Critic agent blocks any number it can't trace back to a query row.
- Designed the Critic agent: it checks every number in a draft answer against the source query rows and sends unsupported claims back for revision, up to 3 rounds.
- Grounded answers in 7 nflverse tables through 16 SQL query plans on a Zetaris Spark cluster, with a DuckDB offline mode.
- Cut full-run latency from 129–350s to 18–135s after finding the model runtime ignored the reasoning-off flag and moving to a version that honored it.
- Co-built a per-user league memory engine from Meterless's published H-MEM spec.
- Shipped with Docker, GitHub Actions CI, timeouts, rule-based fallbacks and JSONL tracing of every step.
