About

Formé deux ans en environnement classifié au Ministère des Armées (alternance, habilitation Défense), puis aguerri dans des contextes volontairement variés et exigeants : banque internationale (BEI — Luxembourg), hôpital multi-sites 24/7, organisme public traitant des données citoyennes, PME industrielle.

Chaque environnement a été pris en main rapidement, du support critique jusqu'à la conception complète d'une architecture de sécurité. En parallèle des postes à temps plein : certifications CEH et CCNA obtenues, plateforme de sécurité développée en Rust, homelab d'expérimentation permanent.

Un parcours construit mission après mission, avec une constante : monter en compétence et en responsabilité à chaque étape.
