À propos de Yaakoubi
Je suis Ghassen Yakoubi, Senior DevOps Engineer et Platform Lead avec plus de 6 ans d’expérience dans la conception et l’exploitation de plateformes cloud natives sécurisées sur Azure, AWS et Kubernetes.
Je suis spécialisé en Platform Engineering, GitOps, Infrastructure as Code, sécurité cloud et architectures hybrides pour des environnements exigeants, notamment dans les secteurs de la finance et du gouvernement.
Actuellement, j’occupe les postes de Senior DevOps Engineer chez Proxym Group et DevOps Team Leader chez Tryloop, où je travaille sur la mise en place de plateformes Kubernetes, OpenShift et Azure à grande échelle. J’accompagne les équipes dans l’automatisation, la sécurisation et la modernisation des infrastructures grâce à Terraform, Bicep, Ansible, ArgoCD et les technologies cloud natives.
Passionné par les défis complexes d’infrastructure, je souhaite continuer à évoluer vers des rôles de leadership en Platform Engineering et Cloud Architecture, en aidant les organisations à construire des plateformes fiables, sécurisées et évolutives.
