Accelerate and secure your deployments on Google Cloud Platform.
With 8 years of experience in tech (5 years in software development and 3 years in Cloud/DevOps engineering), I help companies design, industrialize, and secure their cloud infrastructures.

  • Containerization : Kubernetes expertise (GKE / GKE Autopilot), Cloud Run.
  • Infrastructure as Code (IaC) : Advanced automation with Terraform and Ansible.
  • FinOps & Observability : Auditing, cost optimization (TCO), monitoring (Prometheus, Thanos, Grafana).
Official Certifications:
  • Google Cloud: Professional Cloud Architect, Security Engineer, Network Engineer, Associate Cloud Engineer.
  • CNCF: Certified Kubernetes Application Developer (CKAD), Prometheus Associate
