Freelancer profile translated to English.
Back to original languageAbout Ariel
I am a backend / fullstack developer with over a decade 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 for the development of reactive and hybrid applications from a common codebase.
I also retain strong skills in external development and server-side integration.
Feel free to contact me for your projects.
