Hi! My name is Julien, and I've been a Free Software and Open Source hacker for the last 20 years.

I write a lot of Python code and maintain several Python libraries. 🐍

If you like my work and would like me to continue doing awesome work, this is a great place to sponsor me! 💖

In the past, I hacked on various free software projects, such as Debian, GNU Emacs, or even Common Lisp. I also created the awesome window manager and heavily contributed to OpenStack, an open-source cloud-computing platform written in Python.

If you're interested in what I do, I regularly publish blog posts ✍️. You can also follow me on Twitter 🐦.

Since I write Python code every day, I ended up writing books about it: Serious Python 📘 and Scaling Python 📕!

I also co-founded and run Mergify 🔀, a GitHub service around pull requests automation.

Current Projects

Here are a few projects I maintain and that you can sponsor me for.
