Profile

Lead Platform Engineer with 20+ years in IT, including 10 years focused on cloud-native infrastructure, DevOps, and Site Reliability Engineering (SRE). I design and operate internal developer platforms (IDPs) and Kubernetes environments across AWS, GCP, Azure, and on-premises infrastructure. My work combines Infrastructure as Code (IaC), GitOps, CI/CD, developer self-service, observability, security, incident response, and platform reliability. I remain hands-on from Linux operating systems and networking through Kubernetes and developer platforms, while setting engineering standards, leading technical roadmaps, and mentoring teams. I hold the complete Kubernetes certification track (CKA, CKAD, CKS, KCNA, and KCSA) and have earned Kubestronaut status.

Core Skills

  • Linux systems engineering: 20+ years administering and troubleshooting production Linux environments, including server provisioning, shell automation, networking, access control, monitoring, virtualization, and operational support.
  • Kubernetes platforms: Architecture, provisioning, upgrades, scaling, security, and operations across Amazon EKS, Google GKE, Azure AKS, OpenShift, and self-managed Kubernetes; workload optimization with Karpenter and KEDA.
  • Platform engineering and developer experience: Internal developer platforms (IDPs), reusable platform blueprints, golden paths, platform-as-a-product practices, and developer self-service using Backstage, Crossplane, Helm, and Kubernetes operators.
  • GitOps, CI/CD, and infrastructure automation: Infrastructure as Code (IaC), Argo CD, Terraform, Terragrunt, Crossplane, Atlantis, Helm, Ansible, GitHub Actions, GitLab CI, and CircleCI.
  • Observability and reliability: OpenTelemetry, Prometheus, Grafana, Loki, Tempo, Mimir, Thanos, and Alertmanager for metrics, logs, distributed tracing, alerting, troubleshooting, incident response, and root-cause analysis.
  • Cloud-native security and networking: Istio, Cilium, Kyverno, Trivy, HashiCorp Vault, External Secrets, IAM, secrets management, policy enforcement, and secure service-to-service communication.
  • Technical leadership: Platform architecture, engineering standards, technical roadmaps, people management, mentoring, technical interviews, and cross-team collaboration.
