About Me
With a PhD in nuclear physics, I have acquired solid skills in development and optimization of scientific codes, as well as in software architecture.

After completing my thesis in nuclear physics, I took part in the maintenance of reference codes in radiation protection, core physics and criticality at CS. This experience enabled me to discover all the phases of software development, and to appreciate their importance.

I then joined the CEA as a research engineer and RTE as a designer-developer in the Real Time division. Here, I was able to contribute my expertise to all phases of code production, while continuing to improve my know-how through various training courses and seminars. My main tasks involved the design and development of applications, to maximize performance and enhance the user experience.

Curious, motivated and self-taught by nature, passing on my knowledge is also part of my DNA. I've always been keen to work as part of a team and pass on my knowledge to the teams I work with.
