• Engineered and maintained Azure infrastructure for critical workloads, integrating App Services, Function Apps, Azure SQL, and Service Bus to support scalable, high-availability applications.
  • Implemented blue-green deployments using App Service slot swaps, enabling seamless production cutovers and near-zero downtime during releases.
  • Migrated legacy on-prem applications to Azure, deploying Oracle databases on Azure IaaS VMs by installing Oracle binaries & configuring listeners, bridging gaps where native PaaS lacked support for Oracle.
  • Strengthened security posture by identifying and remediating cloud vulnerabilities, applying best practices around NSGs, private endpoints, and proactive vulnerability scans.
  • Drove cost optimization initiatives by leveraging Kubecost for Kubernetes resource right-sizing and updating VM SKUs, reducing excess spend and securing refunds on over-provisioned resources, resulting in substantial operational savings.

• Engineered a multi-cloud container platform across AWS (EKS), Azure (AKS), and GCP (GKE), standardizing workloads on Kubernetes with secure private networking and integrated CI/CD, observability, and compliance.
• Led Kubernetes upgrades from v1.14 to v1.30 across 150+ clusters, performing detailed middleware compatibility checks to ensure Flux CD, Argo CD, Cilium, Kyverno, CSI drivers, and other tools remained fully operational.
• Automated cluster provisioning with Terraform and custom Python scripts, embedding end-to-end GitOps pipelines, service mesh, observability, and compliance — saving 5,000+ engineering hours annually.
• Identified and corrected node pool inefficiencies and VMSS SKU skews, achieving $100K monthly savings (~$1.2M annually) through strategic resource tuning and Kubecost analytics.
• Managed 500+ ServiceNow requests and resolved 100+ critical incidents, ensuring zero downtime for high-impact workloads and driving platform reliability.
• Enhanced security posture by migrating legacy applications to private networking, removing public endpoints, enforcing workload identity, and deploying Kyverno to uphold compliance standards.
• Implemented Velero backup for Kubernetes across AKS, EKS, and GKE, ensuring disaster recovery readiness and rapid cluster restoration capabilities.
• Worked on Azure-native services such as Function Apps for event-driven automation, Service Bus for decoupled messaging, and integrated App Insights for monitoring application health and performance.
