Small software & data tools, built carefully.

Quadragonal is a one-person practice working on a few long-running tools: a lightweight data pipeline, a search indexer, and assorted infrastructure helpers. We do not advertise, we do not collect analytics, and we do not maintain a mailing list.

Most of what we build is open source. See projects for an overview, or get in touch if you would like to discuss a small piece of work.
