Profile

Lead Platform Engineer with 20+ years in IT, including 10 years focused on DevOps, Site Reliability Engineering (SRE), and cloud-native platforms. I build reliable Kubernetes platforms and internal developer platforms (IDPs) across AWS, GCP, Azure, and on-premises environments, using infrastructure as code, GitOps, and automation to improve developer experience and operational consistency. My experience spans Linux and networking, Kubernetes, Backstage, Crossplane, Argo CD, and OpenTelemetry, as well as platform reliability, observability, and security. I combine hands-on engineering with technical leadership, roadmap ownership, and team mentoring, and I am an advocate for open source and GitOps. 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.
