ABOUT ME

Production experience.
A DevOps mindset.

DevOps-focused Site Reliability Engineer based in Bengaluru, India, with 7+ years of experience across cloud operations, middleware administration, and enterprise production support. My technical focus spans CI/CD, infrastructure as code, container platforms, and operational automation.

At Oracle India, I work as a Site Reliability Engineer II, supporting enterprise production environments across OCI, AWS, and middleware platforms. My work focuses on availability, incident response, troubleshooting, and observability, using tools including WebLogic, Prometheus, Grafana, and Splunk.

My DevOps toolkit includes Jenkins and GitHub for delivery workflows, Terraform and Ansible for infrastructure and configuration, Docker and Kubernetes for container platforms, and Shell, Python, and Groovy for automation. My engineering labs explore cloud infrastructure, container deployments, monitoring, and CI/CD pipelines.

Previously, I held middleware roles at Plus Care International, Quess Corp, and Sathya Sai Team, building a foundation in application support, monitoring, and production troubleshooting that informs my approach to DevOps today.
