I’m a DevOps Engineer with 4+ years of experience in AWS, Kubernetes, Terraform, CI/CD, and Linux Administration. I focus on Infrastructure as Code (IaC), cloud automation, containerization, monitoring, and cost optimization—consistently aiming for scalable, highly available cloud-native systems.

In my current role as Sr. Linux Administrator / DevOps Engineer at Netprophets Cyberworks Pvt Ltd, I designed and implemented AWS infrastructure aligned with the AWS Well-Architected Framework. I reduced AWS infrastructure cost by 30–40% through resource optimization and architecture redesign, provisioned infrastructure with Terraform (reducing manual effort by 70%), and automated deployments via CI/CD pipelines built with Jenkins and GitHub Actions.

I also strengthened operational reliability by implementing Kubernetes for deployment scalability and by creating centralized monitoring using Prometheus and Grafana (reducing incident response time by 40%). Earlier, as a Linux Engineer at Tetra Information Services Pvt Ltd, I managed 40+ Linux servers, hardened configurations, automated SSL renewals and backups, and improved L2/L3 support with proactive Nagios monitoring; before that, as a NOC Engineer at Ngbps Pvt Ltd, I supported OpenStack-based private cloud environments and performed root cause analysis while automating scheduled tasks.
