I have been designing and operating Kubernetes infrastructures in production for over 10 years, on multi-client SaaS platforms where availability is non-negotiable. I cover the entire ops chain: architecture, automation, GitOps, and observability.

Setup of an internal KaaS platform on RKE2 and vCluster integrating virtualization (KubeVirt), distributed storage (Longhorn), and multi-tenancy, with per-tenant isolation, RBAC, and GitOps deployments via FluxCD.

Cloud to on-premise migration

Implementation of a complete DRP on a critical SaaS platform: definition of RTO/RPO, automated failover and restore, infrastructure provisioned via Terraform on Scaleway, configuration driven by Ansible and Puppet.

Multi-tenant Kubernetes Platform

Complete migration of AWS environments to on-premise Kubernetes clusters, maintaining availability and reducing hosting costs.

Kubernetes in production: RKE2, multi-tenant vCluster

Hybrid on-premise and cloud architectures AWS, Scaleway, OVH

Registry and image distribution Harbor, Nexus

GitOps with FluxCD, Jenkins and GitLab CI/CD pipelines

Infrastructure as Code Terraform, Ansible, Puppet, Foreman

Observability Prometheus, Grafana, Alertmanager

Bash automation for daily operations

I build platforms designed to last. I automate what can be automated, document what needs to be documented, and work closely with product and support teams.
