I am French engineer who codes mainly in Python and has some knowledge in C++ and Julia. My work is mainly focused on 3D computer vision problems but I study more broadly DL, ML, RL, and optimization.
My learning of Python started in University through projects and improved greatly after reading Fluent Python: 2nd edition written by Luciano Ramalho and Python Tricks: the book written by Dan Bader. But I have also worked on other programming languages, either in an academic context or by working on projects.
Most of my projects are done in Pytorch, but I have also done internships in Theano and Tensorflow. More recently, I started JaX for a Deep Reinforcement Learning project.
