Find Kotlin engineers and maintainers

The list above ranks the most-starred public Kotlin repositories, drawn from the public GitHub graph. Across 6,325 Kotlin repositories in the public graph, the maintainers, top contributors, and recurring committers are a powerful signal for where Kotlin expertise lives.

Behind every popular Kotlinproject is a small group of people who actually shipped it. They’re the Kotlinengineers, library authors, and infrastructure builders worth knowing — whether you’re hiring, partnering, or doing technical research.

Refolk turns this list into a search. Ask for Kotlin maintainers hiring”, “contributors to Kotlin repos based in Europe”, or “companies whose engineers ship Kotlin” and Refolk returns a ranked shortlist with the commits, repos, and profiles that earned each person a spot.

How this list is built

Refolk searched GitHub for public repositories whose primary language is Kotlin, ranked them by stargazer count, and kept those with at least 100 stars. The list refreshes once a day.
