Hi, I'm Charly. I create, improve, and maintain free software (and other commons). To fund this work I have chosen to rely on the direct support of the community.

Below is a summary of my work.

Free software and Open Data

I am the creator of Liberapay, the website you're on right now, and before that I had contributed a lot to its predecessor (Gittip/Gratipay).

I maintain several other free software projects, mostly written in Python, you can see them on my GitHub profile.

I'm also interested in OpenData. I've been working on legi.py since the database of French laws was released as open data in 2014. One of the things my code does is generate lists of anomalies in the data, to encourage the maintainers to correct them. Since December 2016 the lists are published on anomalies.legilibre.fr.

I'm an ArchLinux user. Throughout the years I've added some packages to the AUR, contributed to the wiki, and a long time ago I wrote the initial implementation of the -Qk command for pacman.

I've been thinking about creating a new programming language for years, as I am unsatisfied with all the languages I've used or looked into. I started writing a compiler for this new language in the last days of 2023, but it'll take years for this work to come to fruition.

Knowledge sharing

I occasionally post on social media and contribute to Wikipedia to share some of the knowledge I've accumulated over the years on various topics.
