Description

I am Djiby, a developer for over 10 years with extensive experience in Backend, particularly in technologies like **PHP**, **Symfony**, **JavaScript**, and **ApiPlatform**.

I have worked for companies such as **L'Etudiant**, **RueDuCommerce**, **FNAC**, and **Alltricks**, all major players in French e-commerce. I helped them develop new projects in various aspects (migration, performance optimization, market expansion, etc.).

I have a particular interest in automation and artificial intelligence.

So, if you have a project, let's talk :)
