FranceWhat I'm looking for
I am a DevSecOps software engineer with 4+ years focused on cyberdefense and cloud provider infrastructure, designing secure Kubernetes-as-a-Service and air-gapped platforms for defense environments.
I architect and implement multi-tenant Kubernetes (OpenShift, K3s, HyperShift) and automation solutions using Terraform, Ansible, Operator SDK, Python and Go, reducing provisioning from days to minutes and delivering resilient, high-throughput data collection systems.
I drive Shift-Left security with tooling like Trivy, Snyk, SonarQube and OPA, mentor junior engineers, and integrate Agentic AI patterns into next-gen workflows while maintaining operational L2/L3 support for multi-tenant environments.
