About

Custom software, built together

A developer since 2005 and an EPITECH graduate, I was lucky enough to join the PrestaShop core team, then to lead the team in charge of partner modules. 23Prod was born in 2012 to help merchants with PrestaShop.

Since then, the playground has grown: business applications and custom software with Symfony, e-commerce with Sylius, and the infrastructure that goes with it (Docker, Kubernetes, CI/CD). With my partners, we also build sovereign products at Obsylabs and deepblock.
