I’m a young french developper living in Nantes and working at GoPro.
My favourite programming language is C++, well modern C++, because before C++11 a lot of things are really frustrating to do and when you have tried C++17, it is hard to use something older. Now that I have tasted C++20 (and a bit of C++23) I think I will never make any pet project in an older standard because it has so much new useful features.
Sometimes I also like to make little projects in javascript (with node.js) or python but I’m not as fluent in these languages as I am in C++. I’m also learning Rust and I think one day I would like to learn Ada.
Also I did some little stuff in C# (with Unity) or in rust but I can’t really say I have any experience in these languages.
