About

A web developer since 2011. Drupal is my speciality, from version 7 to the latest releases, but the foundation is broader: PHP, Symfony and the frameworks that revolve around them, from back office to front end, APIs included.

I work on institutional projects and high-stakes platforms, directly or alongside agencies, mainly between France and Luxembourg. My day-to-day: complex sites, major version migrations, platforms that need to hold up for years.

Cache Rebuild is the shape I gave this practice in 2024: a purely technical expertise company, designed as a reinforcement inside your teams. No marketing, no design: just sharp development. For complete projects, there is the Adevweb collective.
