Thank you, @developer.arm.com, for investing in the future of #Python and the PSF by hosting this year’s CPython sprint– we appreciate your support!

🐍 CPython Core Dev Sprint 2025 wrap:

~50 core devs (yes, Guido too) and invited guests hacking in Cambridge. JIT, free-threading, C-API, endless side discussions.

It's safe to say the best ideas start over coffee and a whiteboard with @python.org: community.arm.com/arm-communit...

After hosting the CPython Core Dev Sprint at Arm, I went to @pyconuk.org in Manchester. I even brought my kids so they could experience a Python conference. 🐍💙

I stepped in last-minute to give my talk on the CPython JIT. 😎

I gave a talk at @europython.eu about “Exploring the CPython JIT” where I go to a journey in the execution pipeline, from the Python source code to native machine code.

Feel free to reach me out if you have any question.

I’m officially a CPython Core Developer! 🐍

I’ve been using Python since 2006 — contributing back was a dream, and now it’s real.
Huge thanks to everyone who supported me, and to Arm for backing me from day one.

It’s not the destination — it’s the journey. 💙
