About Antoine

Independent consultant with over 15 years of experience, I support organizations in their Cloud and DevSecOps transformation projects, from strategic framing to the industrialization of solutions. My background combines a dual expertise: technical (Azure Cloud, AWS, GCP, DevOps, security, complex infrastructures) and management (SAFE, PMP, IT governance, project management).

Accustomed to demanding and international environments (L'Oréal, Infogreffe, BNP, Ministry of Culture, SFR…), I bring real value to complex projects: migration to the Cloud, implementation of secure software factories, IT governance, FinOps optimization and integration of security at the heart of processes.

My approach: rigor, communication and leadership to unite teams, secure deliverables and guarantee the success of digital transformation projects.
