About

Sri Lanka–based DevOps/Platform engineer focused on Kubernetes and AWS who has led real production incidents and recoveries (network-policy-induced asymmetric routing; node pool failure due to CNI upgrade). Built production CI/CD with GitHub Actions (ephemeral self-hosted runners on EKS), ArgoCD, Vault, and Terraform, and led a phased ECS-to-EKS migration including Kafka consumers and MongoDB Atlas private endpoints.

Key Strengths

  • Led end-to-end incident response across application and Kubernetes cluster layers
  • Identified network latency/TCP retransmissions via Datadog and traced root cause to misconfigured network policy/security group causing asymmetric routing
  • Stabilized production outage by pausing automation, coordinating comms, and applying ingress rate limiting
  • Recovered from node pool failure by cordoning/draining nodes and rolling back CNI plugin via Terraform/GitHub Actions
  • Planned and executed phased ECS-to-EKS migration with detailed cutover docs, rollback plans, and stakeholder coordination
  • Built secure, repeatable CI/CD with GitHub Actions (reusable workflows), ArgoCD, Vault, and approval gates tied to change tickets
  • Diagnosed Terraform pipeline failure to IAM permission regression affecting DynamoDB state locking and restored access
