Find Python engineers shipping RAG

The list above ranks the most-starred public Python repositories tagged with the RAG topic, drawn from the public GitHub graph. Across 790 matching repositories, the contributors are a tight cluster of engineers with both Python chops and real RAG experience.

That overlap is rare. Most Python engineers haven’t shipped RAG, and most RAG maintainers don’t write Python. The people on this list’s contributor graph are the ones who do both.

Refolk turns this list into a search. Ask for “Python RAG maintainers hiring” or “Python engineers shipping RAG in 2025” and Refolk returns a ranked shortlist with the commits, profiles, and projects behind each name.

How this list is built

Refolk searched GitHub for public Python repositories tagged with the RAG topic, ranked them by stargazer count, and kept those with at least 25 stars. The list refreshes once a day.
