About Florentin

Looking to secure your Cloud-Native applications without sacrificing development velocity?

As a Cybersecurity Engineer and current CPTO of the software editor CybeDefend, I offer a rare dual expertise: the rigor of an auditor and the pragmatism of a builder. Unlike a traditional consultant, I design complex systems daily, so I understand your operational constraints.

🚀 What I Deliver for You:

*Cloud & Kubernetes Architecture:Design of resilient and "Cloud Agnostic" infrastructures (GCP, OVH, AWS, Scaleway). Deployment of microservices architectures (Go, NestJS, Python, etc.) and securing flows (gRPC, Mesh).

*DevSecOps & Automation:Seamless integration of security into your CI/CD pipelines. Implementation of automated scanners (SAST, DAST, SCA, IaC) and Docker container hardening.

*Access Management (IAM):Implementation of Zero Trust strategies, secrets management (Vault), and granular access control (ReBAC/ABAC).

*AppSec Audit:Code review, vulnerability analysis, and support for technical teams in remediation.


💼 My Field Experience:

*CybeDefend (SaaS):End-to-end creation of an application security platform. K8s architecture, advanced permissions management, and Backend development.

*Accenture (Key Accounts):AppSec & DevSecOps missions for major clients (Luxury, Energy, Public Sector). Audits, training, and industrialization of security.

*Handle Branding (International):Deployment of a high-availability GCP infrastructure with multi-region load balancing (US, Europe, Asia).


🛠 Technical Stack:GCP, Kubernetes, Terraform, Docker, NestJS, Go, Python, Vault/Infisical, Gitlab CI/Github Actions.
