About Sylvain

I am an engineer/doctor in fuel cells/hydrogen with nearly 9 years of experience in artificial intelligence (AI) for experimental data "fitting" (supervised regression learning).

I primarily work in Matlab, Julia, Zig, and C, but I am open to other programming languages as well as other types of machine learning and applications: unsupervised, classification, etc.

My CV is rather oriented towards hydrogen engineering as it is my core business, but I wish to develop an AI activity in fields other than engineering.

I enjoy learning, teaching, programming, modeling, and automating, in a rigorous and structured manner.
