Nagesh Kampati

CME Group (Site Reliability Engineer)

• Strong Site Reliability Engineering (SRE) background, focused on resilience, performance, fault tolerance, and implementing liveness/readiness probes, auto-scaling, and load balancer–based high availability.
• Led cloud migrations to GCP, delivering end-to-end observability using OpenTelemetry, Prometheus, and Grafana, and automating infrastructure with Terraform and Ansible to support resilient systems at scale.
• Deep hands-on expertise in Kubernetes cluster management, governance, and production-grade deployments, managing both stateless and stateful workloads, with data replication and failover strategies.
• Designed UC4-based start and stop schedules for upstream and downstream workloads following GCP migration, enabling controlled environment availability, reduced operational risk, and optimized cloud resource usage.

PayPal (Container Platform Team)

• Setting up DevOps CI/CD pipelines from scratch to automate deployments in hybrid environments (Dev, QA, and Prod) using Git, Maven, Docker, Ansible, and Jenkins.
• Writing Ansible playbooks and Puppet manifests to automate deployments and day-to-day operational tasks to reduce or eliminate manual efforts.
• Responsible for operating and managing large-scale Kubernetes and Apache Mesos clusters by managing control-plane and data-plane components, enabling vertical and horizontal pod autoscaling, and cluster administration using Kubectl commands.
• Implementing monitoring tools such as Splunk, HashiCorp Consul, GCP monitors, and PagerDuty to monitor application and infrastructure metrics.
• Managing 30k Unix-based VMs in public and private cloud environments, and troubleshooting, debugging, and alert handling for system-related and service (systemd and Docker containers) issues.
• Performing 12/7 on-call rotations.
