Back to original languageAbout Xavier
I help SMEs and scale-ups design or modernize their ERP and business back-ends built in PHP (including PHP 5.6 and very legacy applications), gradually evolving them towards more reliable, tested, and secure Laravel bases.
I provide support for existing Laravel applications or old PHP monoliths to stabilize the code, introduce tests (TDD), and guide your teams towards a more robust and maintainable foundation.
I also work on securing Laravel applications (OWASP best practices, role management, data protection), with a specialization in security currently under development.
What I do:
- Design and evolution of ERP / management tools / business back-ends under Laravel.
- Refactoring and maintenance of PHP legacy (including PHP 5.6) towards a modern, more reliable, and testable Laravel foundation.
- Setting up development environments (Docker/Podman) and configuring Apache/PHP server bases for pre-production or production.
Do you have specific needs? Accustomed to taking on complete and complex projects, I develop custom web solutions, from the scoping phase to production, with close support.
Technical Back-end Skills:
- PHP 5.6 / 7 / 8
- Laravel 5 to 12
- MySQL.

- Continuous Integration,
