I am a backend software engineer working at Software Heritage, a non-profit building the universal source code archive.
This primarily involves working on or with the compressed in-memory representation of the entire software development graph, ie. all commits and files in public VCS and package managers supported by Software Heritage. The use-cases I am the most involved with are Provenance ("Given this file's sha1, tell me what commit/repository it comes from") and vulnerability (eg. CVE) tracking.
I also occasionally work on PostgreSQL and Cassandra databases and the CodeMeta ontology for software metadata.
In my free time, I also work on Free Software and open protocols, especially the IRC protocol and its implementations. In particular, I am the lead developer of Limnoria, a full-featured IRC bot based on Supybot. I am the editor of the Modern IRC Specification, I occasionally write specifications for IRCv3, and I maintain the irctest test suite.
I also host an open Mastodon instance: oc.todon.fr
When not in front of my computer, I enjoy (vegetarian) cooking, indoor gardening and hydroponics, and 3D printing. These intersect more than one might think. :)
