Kubernetes Migration Containerized a legacy monolith onto AWS EKS with Helm and autoscaling, cutting deployment time from 2 hours to 15 minutes with zero downtime. 2. Terraform Infrastructure Automation Designed modular Terraform with CI integration and state locking, reducing environment provisioning from 5 days to 45 minutes with zero config drift. 3. Migration from Openshift to ARO. Migrated IBM CP4D from OCP on-prem to Azure Openshift because of resource constraints. 4. CI/CD Pipeline Optimization Refactored pipelines with parallel stages, caching, and shifted-left security, cutting runtime from 40 to 11 minutes and enabling daily releases. 5. Observability Implementation Deployed OpenTelemetry-based logging, tracing, and SLO dashboards on Azure AKS, reducing MTTR from 3 hours to 35 minutes across microservices. 6. Azure AKS to AWS EKS Migration Migrated containerized workloads from AKS to AWS EKS using Terraform and blue-green deployment, completing cutover in under 5 minutes of traffic shift. 7. Cost Optimization on Azure & AWS Rightsized resources, implemented autoscaling, and enforced FinOps governance, reducing monthly cloud spend by 28% and improving utilization by 40%. 8. Internal Developer Platform (IDP) Built a self-service Kubernetes and GitOps platform with RBAC, cutting environment provisioning from 2–3 days to 30 minutes for development teams. 9. DevSecOps Implementation Embedded SAST, DAST, and container scanning into CI pipelines with policy-as-code, reducing security defects by 45% before production without slowing releases. 10. OpenShift On-Prem to AKS Migration Executed phased migration from on-prem OpenShift to Azure AKS, reducing infrastructure management effort by 35% and enabling elastic scalability. 11. Multi-Cloud CI/CD Orchestration Platform Built a centralized CI/CD platform with reusable templates across AWS and Azure, cutting deployment failures by 32% across 40+ services. 12. AI-Driven Cost Optimization Engine Developed an ML-based engine analyzing cloud billing and usage data, reducing spend by 27% and improving forecast accuracy to 90%. 13. Serverless Real-Time Data Processing Pipeline Implemented an event-driven serverless pipeline with enrichment and monitoring, achieving sub-1.5-second latency with zero infrastructure management overhead. 14. GitOps-First Internal Developer Platform (IDP) Delivered a Kubernetes and GitOps platform with self-service templates and RBAC, reducing provisioning from 3 days to 25 minutes with standardized deployments. 15. Edge-Native Deployment Framework Deployed lightweight Kubernetes clusters at edge nodes with progressive CI/CD rollout, reducing latency by 40% and improving resilience during network interruptions. 16.
