What I'm looking for

I’m looking for a role where I can own AWS cloud governance and security, automate operations to cut investigation time, lead reliable deployments and disaster recovery, and collaborate closely with cross-functional teams to raise security posture.

I’m a Cloud Operations and Security Engineer with experience designing, deploying, troubleshooting, and governing AWS cloud solutions for enterprise customers across large-scale environments. I own infrastructure governance, security principles, and IaC-based configuration delivery, coordinating across application, infrastructure, and security teams.

I focus on automation that reduces operational burden—my infrastructure deployment procedures and agent SOPs have saved 30+ hours per month and reduced investigation turnaround time by 60%. I’ve also led security posture improvements from 45% to 95%, performed zero-down time upgrades for EKS and RDS, and planned disaster recovery to meet RTO/RPO/SLA requirements while mentoring teams and improving incident outcomes through strong troubleshooting.
