I am a young engineer & a Ph.D. student, and you are welcome to my web-portfolio.

I currently work as a Ph.D. student at the Orange company, in collaboration with INRIA labs (LACODAM). In the context of servers & infrastructure performances, I manipulate Time Series to do predictions. I code Machine Learning algorithms and user interfaces to improve the Capacity Planning at Orange.

I talk Scala, I am a DevOps, I love CI, FP, Ansible/Jenkins/Docker, I build tested & stable software.

You will find on this website some information about me, my skills, and about some of my projects.
