About Julien

Full Stack Developer, passionate about the web and new technologies, I work on website and e-commerce projects, both in development, maintenance, and production deployment.

Accustomed to working on varied projects, I have developed good autonomy and the ability to find solutions adapted to business needs, while maintaining clear communication with teams and clients.

My skill set covers front-end and back-end development, working on e-commerce CMS (Magento, Prestashop, Shopify), as well as deploying and maintaining server applications.
I am also interested in innovative solutions, particularly around AI and automation.
