Experience

DevOps Support Engineer - Tata Consultancy Services (TCS) - Bengaluru, India

(2022-05)

AWS Infrastructure: Managed AWS cloud infrastructure (EC2, S3, RDS, ELB, EBS, IAM, VPC) across production and nonproduction environments, maintaining 99.9% uptime and consistent SLA delivery.
Containers & Kubernetes: Containerized application workloads using Docker and deployed them on Kubernetes (EKS), working with deployments, services, pods, and configurations — improving infrastructure resource utilization by 35% and enabling on-demand environment provisioning.
Monitoring & Observability: Built and maintained Prometheus and Grafana dashboards for real-time visibility into application and infrastructure health, and configured AWS CloudWatch metrics, alarms, and log groups across EC2, RDS, and EKS workloads — reducing mean time to detect (MTTD) production incidents by 40%.
Log Analysis & Alerting: Set up centralized logging and analysis using the ELK Stack (Elasticsearch, Logstash, Kibana), and configured proactive alerting rules and on-call notifications to surface anomalies and error trends before they impacted users, supporting faster root cause analysis during incidents.
CI/CD: Built GitLab CI/CD pipelines for automated build, test, and deployment workflows — reducing release turnaround by 60% and enabling daily deployments instead of weekly releases.
Linux & Shell Scripting: Authored 20+ shell scripts automating Linux admin tasks (log rotation, health checks, disk monitoring, user provisioning), recovering approximately 10 hours/week of manual operational effort.
Middleware Administration: Administered IBM WebSphere, Tomcat, JBoss, RabbitMQ, and IBM MQ middleware platforms supporting enterprise application deployments and runtime troubleshooting across multiple client environments.
Disaster Recovery & Incident Management: Executed disaster recovery drills, maintained infrastructure runbooks, and coordinated incident response — consistently meeting RTO/RPO targets across all production environments.
