I’m a DevOps / Systems Engineer with 3.10+ years of experience building and managing cloud infrastructure and CI/CD pipelines across AWS and hybrid environments. I focus on CI/CD pipeline design, Terraform-driven IaC, and Kubernetes (EKS) orchestration to help teams ship faster with confidence.

At Unisys, I set up and maintained CI/CD pipelines using Jenkins & GitHub Actions across hybrid infrastructure (mainframe batch + AWS microservices). This took release cycles from 3 days to under 6 hours, removing manual work from building, testing, and deploying services.

I provision and manage AWS cloud infrastructure (EC2, S3, RDS, IAM, VPC) using Terraform and CloudFormation, reducing manual config errors by 30% and cutting environment provisioning time. I also implement end-to-end observability with Prometheus, Grafana, and CloudWatch, plus SonarQube in CI pipelines—reducing critical incident response time by 35% and vulnerability exposure from weeks to 48 hours.

I administer Unisys OS 2200 mainframe and Linux/AWS environments across production, test, and development—resolving 95% of incidents within SLA, reducing system downtime by 25%, and holding uptime at 99.9% through regular monitoring and early fixes. In my projects, I’ve automated AWS EKS infrastructure and CI/CD, built three-tier Kubernetes web apps with auto-scaling, and developed an AI-assisted monitoring approach that improved MTTR by 40%.
