Find C engineers shipping Compilers

The list above ranks the most-starred public C repositories tagged with the Compilers topic, drawn from the public GitHub graph. Across 233 matching repositories, the contributors are a tight cluster of engineers with both C chops and real Compilers experience.

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

Refolk turns this list into a search. Ask for “C Compilers maintainers hiring” or “C engineers shipping Compilers 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 C repositories tagged with the Compilers topic, ranked them by stargazer count, and kept those with at least 25 stars. The list refreshes once a day.
