NYC Taxi ELT
A pipeline that loads NYC taxi-trip Parquet files into Postgres, then transforms them in medallion layers (bronze → silver → gold) into star-schema fact and dimension marts with dbt. dbt tests check every build, Airflow on Docker Compose orchestrates it, and reloads are idempotent.
Parquet → Postgres → dbt · medallion layers · Airflow on Docker Compose
I wanted a public, end-to-end reference build of the modern data stack: the same patterns I use at work, but fully open.
