Director & AI/ML Platform / MLOps Engineer at GeoCloudTech | Kubestronaut | Kubernetes, DevSecOps and MLOps for regulated industries

I'm an AI/ML Platform and MLOps Engineer and a Kubestronaut, with 13+ years in IT and 5+ in DevOps and DevSecOps. Through my consultancy, GeoCloudTech, I design secure, highly available Kubernetes platforms for regulated industries, on cloud and on-premises. What I build: - Kubernetes platforms: RKE2, AKS, EKS, GKE - MLOps: Kubeflow, KServe, MLflow, NVIDIA GPU Operator - DevSecOps: Vault, Kyverno, KubeArmor, Trivy, signed supply chains with Tekton and Cosign - GitOps and automation: Argo CD, Flux, Terraform, Ansible - Storage and identity: Rook Ceph, CloudNativePG, Keycloak - Observability and networking: Prometheus, OpenTelemetry, Cilium, Istio Most of what I publish comes from my multi-datacentre homelab: RKE2 on Proxmox, run through GitOps. My rule: build it, break it, understand it, then harden it. Every article is a real build, traps included. Certifications: Kubestronaut (CKA, CKAD, CKS, KCNA, KCSA), HashiCorp Terraform Associate.
