Data scientist and machine learning engineer with a PhD in machine learning from the University of Technology of Troyes. I specialize in NLP, LLM, and computer vision. I have worked on multiple industrial projects in various sectors such as mass retail and aeronautics. Autonomous and self-taught, I have an appetite for subjects presenting scientific and technical challenges.
I completed my PhD on an NLP topic as part of a collaboration between several companies and laboratories.
I then worked as a consultant on topics such as NLP/LLM, Computer Vision, recommendation, pricing, time series prediction, etc.
I prefer to work remotely, but I can travel to the site as needed.
