About Ariel

I am a backend / full-stack developer with over ten years of experience in various fields (web, ticketing, voip, security, health, energy, real estate...)

With a university background, up to an M.Sc (formerly DEA) in Computer Science from the University Pierre and Marie Curie (Paris 6 - Sorbonne University), I adapt quite easily and quickly to new technologies.

For over 10 years, I have specialized in Javascript platforms such as Node.js / React, which allow the development of reactive and hybrid applications from a common codebase.

I also maintain strong skills in external development and server-side integration.

Do not hesitate to contact me for your projects.

It was a real pleasure to work with Ariel. We were stuck on blocking Node.js processes that were slowing down our application. Ariel quickly identified and solved our problem in less than 2 days and gave us optimization advice. He remains attentive and answers our questions even after the mission. I highly recommend entrusting him with a mission if you are looking for an efficient and serious partner.
