Hi! My name is Julien, and I've been a Free Software and Open Source hacker for the last 20 years. During the day, I work as a Principal Software Engineer at Redย Hat ๐Ÿ’ป, hacking on Gnocchi and Python software ๐Ÿ.

Since I write Python code every day, I ended up writing books about it: Serious Python ๐Ÿ“˜ and Scaling Python ๐Ÿ“•!

I co-founded and run Mergify ๐Ÿ”€, a GitHub service around automation.

Before that, I hacked on various free software projects, such as Debian, where I've been a developer since 2002, GNU Emacs or even Common Lisp. I also contributed heavily to OpenStack, an open-source cloud-computing platform.

Once a while, I give talks about all of that.

I also enjoy playing FPS games ๐ŸŽฎ, running half-marathon ๐Ÿ‘Ÿ, consider myself as a foodie ๐Ÿฅ˜ and an amateur mixologist ๐Ÿธ!
