What I'm looking for

I seek a senior SRE/DevOps role focused on cloud-native infrastructure, reliability, security, and team leadership, with opportunities to modernize CI/CD and improve operational excellence.

I am a Senior Site Reliability and DevOps engineer with over 10 years of experience designing, automating, and securing large-scale distributed systems across AWS, GCP, and Azure. I have a proven track record building highly available, compliant, and resilient cloud infrastructures, improving provisioning time by 60% and maintaining >99.95% uptime for production workloads.

I lead incident response and crisis management, drive CI/CD modernization, and mentor teams to deliver operational excellence. My work has included Terraform-based IaC, Kubernetes (EKS) operations, security hardening, and migrations that reduced release cycles by 40% while enhancing deployment reliability.
