About Sébastien
DevOps Engineer avec 7 ans d’expérience, j’accompagne les entreprises dans la conception, l’industrialisation et l’optimisation de leurs infrastructures cloud. J’ai travaillé sur l’ensemble des principaux environnements (AWS, GCP, Azure), avec une expertise particulière sur AWS.
Spécialisé en Kubernetes, je conçois et opère des plateformes robustes, scalables et sécurisées, adaptées aux enjeux modernes de delivery et de performance. Mon approche s’inscrit pleinement dans une démarche de Platform Engineering : créer des outils et des environnements qui simplifient la vie des équipes de développement tout en garantissant fiabilité et efficacité.
Passionné par l’innovation, je m’intéresse également de près aux sujets liés à l’intelligence artificielle et à leur intégration dans les architectures cloud.
Mon objectif : vous aider à accélérer vos déploiements, améliorer la résilience de vos systèmes et tirer le meilleur parti de votre infrastructure.
