About Me

DevOps Engineer with 4+ years of professional experience, 3+ of them in DevOps, building and running cloud infrastructure across AWS, Azure and GCP. Hands-on with Kubernetes (EKS, AKS, GKE and self-managed kubeadm clusters), Docker, Helm, Terraform and Ansible, and CI/CD pipelines in Jenkins, Azure DevOps, GitLab CI and Argo CD. Delivered on-premises to cloud migrations for enterprise and banking platforms, with production on-call and observability experience.

Featured Project:

HCL Discover on Mixed Windows/Linux Kubernetes

AKS Jenkins Windows + Linux Nodes

Deployed and operated a digital experience analytics and session-replay platform on Azure Kubernetes Service, across a cluster running both Windows and Linux node pools. The product requires both OS types, so the work covered OS-specific scheduling, node affinity and cross-platform networking on shared infrastructure.

Key Responsibilities

• Mixed-OS node pool scheduling and affinity
• Helm chart packaging, version-controlled in GitHub
• Docker images published to a Harbor private registry
• Jenkins for CI, Argo CD for GitOps delivery
