Vert.x in Action book cover

I am a Principal Software Engineer at Red Hat. I am primarily working on reactive things and the Eclipse Vert.x project. I am based in Lyon, France.

I am “on leave” from INSA Lyon and the CITI Laboratory where I was an Associate Professor in computer science and engineering. I have held various teaching, research, managing and executive positions while at INSA.
