Viswa Teja P.

•Participated in 24/7 on-call rotations as a production standby engineer — responded to Datadog/CloudWatch alerts during off-hours, performed first-level triage, and escalated with full incident context to minimize MTTR across critical services. •Joined and actively contributed to production bridge calls during Sev-1/Sev-2 incidents — coordinated with cross-functional teams (Dev, Infra, Security), communicated live system status, tracked action items, and documented post-incident timelines and RCAs in Confluence. •Diagnosed and resolved Kubernetes CrashLoopBackOff, OOMKilled, and pod scheduling failures across EKS clusters; investigated container logs, resource limits, and liveness/readiness probe misconfigurations to restore service stability within SLA windows. •Monitored and triaged AWS services and Linux server health using Datadog and CloudWatch — tracked CPU, memory, disk I/O, and network metrics; tuned alert thresholds to reduce false positives and improve on-call response quality. •Managed and maintained CI/CD pipelines in Jenkins — reviewed and merged Git pull requests, resolved pipeline failures, handled broken builds, and ensured smooth promotion of code across dev, staging, and production environments. •Provisioned and managed cloud infrastructure on AWS (EC2, EKS, VPC, S3, Security Groups) using Terraform; handled infrastructure change requests end-to-end from Git PR review to apply and post-deployment validation. •Administered Linux servers — performed OS patching, package upgrades, service restarts, log analysis via journalctl/syslog, and resolved SSH/permission/networking issues across production and staging environments. •Operated and troubleshot Rancher-managed Kubernetes clusters — monitored workload health, investigated service degradations, restarted failed deployments, and escalated persistent issues with full context documentation in Jira. .
