Hello there 👋 ! I am a 🇫🇷 French passionate coder on GitHub (also Bitbucket & GitLab!), and I love programming as well as teaching! I've been a big fan of 🐍 Python since 2011, and I love 🐫 OCaml and Bash as my favorite programming languages! I'm a proud Bash user since 2011 too, on a daily basis!

I started programming on my Texas Instruments graphical calculator, back in 2008, and since then I've kept an interest for this field: see these .nwa apps for Numworks and this project: OMicroB for Numworks (this thread too).

Since 2021, I am now a full-time professor of Computer Science in Classes Préparatoires (in MP2I), in Lycée Kléber in Strasbourg (France). I teach computer science at "baccalauréat" +1 level, for one class of 48 students aged between 17 and 19, and I LOVE THIS JOB!

In 2019/20 and 2020/21, I was a junior professor in Computer Science (and Mathematics) at ENS de Rennes in France. Before that, I studied for like 10 years 😂.

Before that, I pursued a Ph.D (phd.pdf) in telecommunications, applied mathematics, machine learning and computer science (yes, all that), at the engineering school CentraleSupélec in Rennes and at Inria in Lille since 2016 to 2019, and I graduated in November 2019. I wrote research articles, with a dozen publications in various national and international conferences and two journals articles, and research software. I continued doing some research after my PhD defense, but I had to stop completely in 2021.

Outside of computer science and teaching, I love biking & hiking, traveling by hitch-hiking and cooking (I'm pro vegetarian!), fighting against the climate crisis and polluters, on a daily basis, on both personal associative and political levels, etc. 🏠 I regularly travel to the beautiful city of Briançon (during holidays), otherwise I now live full-time in Strasbourg. I'm a strong believer in the importance of 💚 ecology, especially reducing waste at a personal level, and local and national political actions. Bien sûr, I like video games, science fiction and fantasy! 🚀 I used to write a lot on my blog.

I'm a big fan of Magic: the Gathering, and long-time green/white "Timmy" player! I'm now an official Magic judge (Level L1), since 2023. Pauper, Modern or EDH, sealed and cube (limited) are my favorite formats! I play regularly at this awesome place in Briançon where we organize drafts, and in Strasbourg, I play weekly at Vent Divin, Dooz TCG and Baraka Jeux and other great locations! I am the secretary and an active member of two local associations for Magic: the Gathering, in Strasbourg: 1. Les Arpenteurs de Strasbourg, since 2023, 2. and also I'm a founding member of Cartes Flambées in 2025. Some of my deck lists were hosted here on GitHub, and they are also here on Moxfield (@Naereen).

💻 I work on Dell and HP laptops, using XUbuntu 22.04+, coding on VSCode, 🎵 listening to music with gmusicbrowser (and using this homemade software). Since 2011, I write a lot of tiny CLI scripts, and I build my website using sphinx. 📝 I love all of mathematics, I teach a bit of maths on a weekly basis. I studied a lot of maths in my twenties, and I got the French national competitive exam for teaching ("agrégation") in 2014, with a major in maths and asecind major in theoretical Computer Science. Since then I've helped writing a very good maths book for Agrégation and license/master level maths (in 🇫🇷 French), and this other one too. 🤣 I'm a big fan of memes, and various TV shows, movies and video-games.
