I’m a results-driven Senior DevOps Engineer with 9+ years of experience designing, deploying, and automating enterprise-grade cloud infrastructure. I’m a specialist in Azure Cloud with 5+ years dedicated to Infrastructure as Code (Terraform), CI/CD automation, and security-first DevOps practices.

At Persistent Systems (@ Microsoft), I’m leading workload migration from AWS EC2 to Azure Virtual Machines with zero-downtime transitions, rollback strategies, and cut-over planning. I architect modular, reusable Terraform for Dev/Test/Prod, build multi-stage Azure DevOps CI/CD (including security scanning and deployment gates), and integrate centralized secrets and certificates via Azure Key Vault.

Previously at Ztek Inc, I designed and deployed centralized, secure Azure infrastructure using modular Terraform—covering VNets, VMs, AKS, Key Vault, NSGs, Storage Accounts, and NICs. I automated security enforcement with Terraform, PowerShell, and Azure Policy to harden environments, and implemented logging and alerting through Azure Monitor, Log Analytics, and Application Insights to support proactive incident response.

Earlier at Virtusa, I managed Azure cloud infrastructure for multiple business-critical applications and maintained high availability using strong architectures. I authored Terraform scripts to reduce manual effort, enforced RBAC and least-privilege access, and supported on-premises to Azure migrations focused on performance, scalability, and security.
