I’d like to propose promoting Stan Ulbrych (@Stanfromireland) to core developer.
If you’ve been active in the repo lately you probably ran into this enthusiastic triager. I’m now at the proverbial point where applying his “I’d merge this” suggestions feel like a chore – and cases where I disagree feel like nitpicking.
Stan started contributing at the end of 2024, was promoted to triager in June, and accumulated 340+ commits in main.
He’s active in datetime (to the point where @pganssle asked about promoting him a few months back), oss-fuzz, security (as a PSRT member), the Devguide & documentation, and lots of general bug triage.
If Stan is promoted, I of course intend to continue mentoring him. And to be mentored by him, given his breadth of interest.
Enthusiastic +1 for Stan! I’ve had occasion to correspond with him offline about several Python code and doc issues, and he’s always been knowledgable, insightful, and a pleasure to work with.
A huge +1 to Stan’s nomination. Stan has been doing awesome and very thorough work across the codebase but also across the Python org on GitHub (he’s also been active on buildmaster-config, and maintains buildbots of his own).
I think he’d make an amazing addition to our team!
I enthusiastically support promoting Stan. They have grown so much this past year, and I am confident that they will be a positive addition to the core team. His attention to detail is excellent.
I would also like to give a strong endorsement to this promotion. Stan’s contributions are marked by his dedication (as you’ve seen from his contribution stats) and the fact that he’s a very quick study. Over a fairly short period of time he’s gotten up to speed enough on datetime and zoneinfo that I really respect his judgement and knowledge. It’s to the point that I recently asked him to give a review of this albatross of a massive PR to dateutil that I’ve been working on for 5 years, which he reviewed very quickly and gave very good comments.
As additional evidence of how much trust he has earned, we added him to CODEOWNERS for dates and times and also we recently gave him a commit bit on the tzdata repo[1] because it was useful for him to help keep that up to date (and also he made a bunch of awesome improvements to the process over there as well).
I’ve been unusually pressed for time these last few years and haven’t been able to devote nearly as much time to open source maintenance as I would prefer. Stan has really stepped up, both in volunteering and in finding the places that need volunteers. I only wish that I had had more time to help mentor Stan and to be less of a bottleneck in some of his workflows, so I’m very excited to finally see this vote.
Thanks for @encukou for stepping up to mentor him and for putting it up for a vote.

If you had asked me a year ago, I would have been against it. You can see that many of his earliest PRs were rejected. Stan had a habit of jumping into coding before deciding whether the problem was worth solving and whether the proposed changes were the right solution. That’s not what we want in a core developer, the ability to evaluate which changes are unnecessary is an important skill. But he has become more experienced over the year. I have no questions about his coding skills. He also has a great personality.
A very happy +1 from me. I have had the pleasure of working closely with Stan over the past year and a half, and I have watched him grow enormously in that time.
What I find remarkable is not just all the different areas of his contributions across the parser, buildbots, Tachyon and more, but how he has learned on how to approach problems. He has gone from someone who would dive straight into the code to someone who takes the time to think carefully about whether a change is the right one. That evolution is exactly what we want to see IMHO.
A few months ago Stan asked me, somewhat tentatively, whether I thought he had the potential to be a core developer someday. I said yes then, and I am very glad a lot of people in the the team so far share the feeling.
