Ken Jin and I would like to promote Chris Eibl (@chris-eibl on GitHub) to the core team.
Chris has been active on the project since January 2025, and has authored 78 merged PRs across the Python organization, been involved in nearly 200 PRs, and participated in close to 100 issues. He joined the triage team in April 2025 and has been a steady, reliable presence ever since.
Chris’s deepest expertise is on Windows, which has been enormously valuable to us. He’s worked on keeping CI and the buildbots green on Windows, and was deeply involved in untangling some of the gnarlier corners of PyREPL on that platform. A particular highlight from his clang-cl work is getting PGO for clang-cl merged, which was instrumental for the Faster CPython team’s tail-calling interpreter work.
On the performance side, he’s landed bytecode specializations and other optimizations (#143389, #129301, #144826), and infrastructural improvements to improve the quality and size of JIT stencils (#142043, #142052, #146338). He’s also helped get huge pages working properly on Windows (#144928), and pitched in on HACL SIMD work (#130213), where HACL* maintainer Jonathan Protzenko credited him as one of the Python-side champions of that integration. Personally, I’ve really appreciated Chris’s help getting the JIT in good shape on Windows. It’s an area where we’ve historically had thinner coverage, and his persistence and platform expertise have made a meaningful difference. I trust his judgment on the work he picks up, and I trust his decisions in code review.
Chris shows up for the work that needs doing, sticks with hard problems, and helps where help is needed. In my mind, that’s exactly the kind of contributor we want on the core team.
I’m confident Chris will make an excellent addition to the team.
