Back to original languageAbout Quentin
My favorite languages today are C, C++, and Python after having experimented with various technologies over the years. I have been using Linux daily for about fifteen years. I received extensive training in fundamental computer science and completed a PhD in cryptography to refine my understanding.
I have worked with strong rigor constraints:
- in a large group (Engie), for electricity price prediction, for client contract appraisal, as a Python tech lead
- a startup (TrustInSoft), for bug detection in critical programs using formal methods, as a C and C++ expert
