Problem
Most pipelines need a cloud bill and an engineer on call.
What I built
A scheduled GitHub Action that transforms CSVs to Parquet with DuckDB and commits the output.
Result
A durable, $0 pipeline a non-engineer can trigger and inspect.
What I'd do differently
Add schema validation so bad input fails loudly instead of silently.
