Atlanta Transit Agent — Winner, Best Use of Atlanta Open Data at Hack RenderATL (MLH), August 2026. A conversational agent over Atlanta civic data. Batch pipeline aggregating 2.4M MARTA GTFS stop-times to 49K per-stop-per-day rows with DuckDB spatial joins, a 19-task orchestrated harvest with retry policies differentiated by failure mode, and eval rubrics that stop the agent citing figures its query never returned. I set out to show MARTA underserves Atlanta's poorest neighbourhoods; the data said otherwise, and the README reports that instead.
