Services

Data pipelines & ETL

Reliable, versioned, analysis-ready data out of scattered or poorly documented sources, with automated ingestion and transformation.

How I work

  1. Short brief

    Goal, available data, deadline. I reply within one business day with questions or a proposal.

  2. Early prototype

    Something working on your real data in days, not months. It validates direction before committing scope.

  3. Iterate & hand off

    Short cycles with visible results. What's left is code, documentation, and whatever the system needs to run on its own.

If any of this matches what you need, write me.
