What I'm looking for

I’m looking for a role where I can architect resilient cloud platforms (Vault, Azure, Kubernetes) and deliver reliable infrastructure-as-code, with the chance to lead hands-on engineering and use modern AI-assisted workflows to move fast.

I’m a cloud and platform engineer with 10+ years building production infrastructure for BNP Paribas, Société Générale, and Energisme (via Astek and Devoteam). My deep expertise is HashiCorp Vault—multi-region, DR, and HSM integration—along with Azure and Kubernetes, delivered through infrastructure-as-code at scale.

I’ve scaled VMware vRA provisioning to ~1,000 operations per week and 10,000 production VMs at a 95% SLA, and I’ve led a 10-engineer Scrum team delivering Société Générale’s enterprise DNS-as-a-Service. I’m equally effective as a solo founder, technical lead, or hands-on contributor—right now building EYA, a West African multi-vertical mobile super-app with AI-augmented engineering (Claude Code) for deep fluency in modern AI-assisted workflows.
