I build secure AWS hybrid infrastructure and automate reliable cloud deployments with Terraform, Ansible, and GitLab CI/CD.

At Cognizant, I built hybrid AWS infrastructure for PSEG Long Island's SAP workload migration, provisioning 45+ EC2 instances across three VPCs and connecting two on-premises data centers through Transit Gateway and BGP-enabled VPNs.

I replaced manual Terraform deployments with GitLab CI/CD pipelines for Docker builds, Trivy scanning, ECR pushes, and Blue/Green deployments. I also automated CIS-hardened Golden AMI builds with Packer, cutting instance boot time from 12 to 2 minutes and deployment lead time by 80%.

Across Clinisys, ARC Document Solutions, MModal, and Evolving Systems, I've supported regulated healthcare, SaaS, and production Linux environments through monitoring, incident response, infrastructure automation, security hardening, documentation, and mentoring junior engineers.
