About Julien

Hello,

Passionate about the Web since 1996 and driven by curiosity, I master all stages of a web application project (institutional site, e-commerce site, or management application) in both its methodological and technical aspects.

From technical assistance to maintenance in operational condition, I possess both functional and technical skills that allow me to bridge the gap between business needs and their implementation on the Web.

Convinced of the qualities of Free and Open Source software for a long time, the solutions I recommend and implement are always based on products from this community, and the LAMP environment is my preferred playground.

Finally, my various experiences in project management, whether as a service provider or client-side, have provided me with the necessary skills for managing technical teams as well as overseeing suppliers.
