About

I’m a Senior DevOps Engineer at Copart Deutschland in Karlsruhe, having joined Copart’s India Technology Center in Hyderabad in 2017. My background is in build and release engineering: CI/CD for Agile teams across production and non-production environments.

Day to day I build and maintain Jenkins pipelines integrated with GitHub, create Docker images and manage the registry, and run and troubleshoot Kubernetes in production. I automate recurring work with Ansible playbooks and shell scripts, and administer the Linux (CentOS / Red Hat) servers, Tomcat and WebLogic application servers, and NGINX reverse proxies and load balancers underneath.

I’m on the front line when production needs attention: responding to alerts, coordinating incident bridges, digging through Sumo Logic and Scalyr logs to troubleshoot Java applications, tracking down Kafka consumer lag, and remediating security vulnerabilities across the infrastructure.
