Career Profile
Senior DevOps Engineer with 11+ years of experience in Cloud Platform Engineering, Kubernetes operations, CI/CD architecture, OpenStack, and large-scale infrastructure environments. Currently part of IBM Cloud VPC Platform Team, leading Kubernetes-based platform deployments, new region/mzone bring-up, CI/CD ownership (Jenkins & Tekton), automation engineering, and production-grade release management. Strong expertise in platform reliability, incident response, automation using Python, and multi-region infrastructure scaling
Education
Experience
- Led end-to-end regional expansions for IBM Cloud VPC (Montreal, Madrid, Mumbai, Chennai DC), managing infrastructure readiness and zero-impact production cutovers.
- Architected Kubernetes control-planes and networking configurations for global-scale compute services, managing clusters with 1,000+ worker nodes.
- Reduced deployment windows by 40% by re-engineering CD pipelines to parallelize zone/zonelet rollouts across complex regional topologies.
- Modernized CI/CD infrastructure by using Terraform to migrate legacy Jenkins workflows to IBM OnePipeline (Tekton), automating toolchain creation.
- Developed Terraform-managed health checks for Next Gen Data Centers (NGDC), executing hourly validations of pod readiness and node status.
- Engineered GitOps regional promotion using K8s CronJobs and Bash to automate delta comparisons and PR creation between environments.
- Automated release validation via Tekton, implementing environment locking and automated testing for PR auto-merging across global regions.
- Decreased release cycle times by 1+ hour per PR by implementing label-driven “skip-pre-check” logic for back-to-back regional deployments.
- Developed Python-based security monitoring to audit HashiCorp Vault secrets, triggering Slack alerts 5 days prior to certificate expiration.
- Built Python health-check suites to automate real-time validation of pod status, node readiness, and control-plane stability.
- Optimized CI/CD workflows using Jenkins and Tekton, introducing label-based skipping to bypass validated zones during deployment reruns.
- Managed 24/7 high-availability operations, leading incident triage, RCA, and rapid recovery via PagerDuty for critical VPC services.
- Improved MTTR and platform stability by partnering with SRE teams to enhance monitoring coverage and proactive alerting thresholds.
- Collaborated with Networking and Security teams to ensure architectural compliance, service onboarding, and strict regulatory readiness.
- Scaled global compute capacity by automating node provisioning and edge-layer expansions to meet increasing workload demands.
- Standardized deployment orchestration across Pre-Integration, Staging, and Production, ensuring consistency in microservice delivery.
- Enhanced developer productivity by building self-service automation tools that reduced manual infrastructure overhead by 30%+.
- Implemented automated rollback strategies and validation gates to significantly reduce change failure rates in production environments.
- Successfully operationalized multiple cloud regions with production-grade reliability, contributing to the growth of IBM Cloud VPC.
