Available for new missions starting November 2026.
Ensure the high availability and resilience of your critical infrastructures.
Cloud Engineer (AWS) & SRE with proven experience in demanding environments (Banking, Industry), I support companies in securing their production, optimizing their performance, and automating their deployments.
My approach is pragmatic: "Do it right the first time". I design scalable, auditable architectures designed for "Day 2 Operations" (Run).
My areas of expertise:
Cloud & Resilience (AWS): Migration of massive databases (e.g., 12TB in a banking environment) without service interruption. Architecture of high-performance Disaster Recovery Plans (DRP/BCP) (RTO < 10 min via AWS DRS, Cross-region Snapshots).
DevOps & CI/CD: Complete redesign and automation of delivery pipelines (Azure DevOps, GitHub Actions, GitLab CI). Elimination of deployment technical debt (reduction of build times by up to -85%).
Observability & SRE: Implementation of real-time monitoring and end-to-end traceability (Grafana, Loki) to minimize MTTD (Mean Time To Detect) to a few seconds.
Infrastructure as Code (IaC): Clean and reproducible provisioning (Terraform, Docker/Kubernetes containerization).
My preferred technical stack:
AWS, Terraform, Docker, CI/CD (Azure DevOps/Git), PostgreSQL, Linux, Bash/KSH.
Whether you need to secure unstable legacy systems, migrate to the Cloud without data loss, or accelerate your Time-to-Market with robust pipelines, let's discuss your architecture.
