Summary

With 20 years of experience in High-Performance Computing (HPC), I transitioned from academia to the private sector years ago. I have worked extensively with various technologies and continually strive to expand my knowledge. Proficient in both legacy and modern technologies, my expertise spans hardware, development, parallelization, cloud computing, and infrastructure deployment. interested in robust, efficient, and resilient infrastructures, I place great importance on their optimization, administration, and evolution. Although I do not yet have experience or certifications in every tech stack, I learn very quickly and possess strong adaptability, which allows me to rapidly become proficient in the required technologies. Available from the end of the year for remote or hybrid assignments, I prioritize long-term projects that enable me to support a company on a sustainable basis — whether as operational reinforcement or an operational Tech Lead. Open to full-time, long-term freelance opportunities in France and internationally (usually via a staffing agency or an IT services company). Feel free to contact me to discuss your projects.
