About
A full-stack profile with a strong back-end foundation.
I am 25 and hold a Master’s degree in Cybersecurity from Université Catholique de Lille (2024–2026). I am looking for a PHP/Symfony, back-end or full-stack developer role and am also open to freelance projects.
From September 2024 to September 2026, I worked at CNAM (France’s national health insurance body) in Valenciennes as a project assistant and Symfony/PHP developer through an apprenticeship. My work covered business intranet applications, back-end development, front-end contributions and corrective and adaptive maintenance.
During my full-stack apprenticeship at sweeek (2023–2024), using Symfony and Angular, I regularly worked with Docker and GitLab CI/CD and automated releases. I also gained hands-on experience with Kubernetes. My internship at Falk Esport (2023), using Laravel, added to this web development experience.

Cybersecurity & AppSec
A security mindset applied to development.
My Master’s in Cybersecurity at Université Catholique de Lille gave me practical security experience through CTFs, hands-on labs and controlled scenarios, including Airbus CyberRange with Exegol and a Linux VPN. My background also includes the CSNA Stormshield certification.
These experiences help me understand an attacker’s approach and apply that perspective to development: input validation, access control, role management, sensitive data protection, API security and OWASP good practices.
