Work Experience
DevOps & Cloud Engineer
Kyndryl
- Managed core AWS services (EC2, EKS, S3, ELB, VPC, CloudWatch, IAM) to deliver secure, scalable environments for enterprise applications; implemented S3 and EBS snapshot strategies for data persistence and recovery.
- Built and managed Kubernetes clusters from scratch, configuring node pools and orchestrating deployments, StatefulSets, services, and ingress controllers, with integrated monitoring to ensure high availability and performance.
- Upgraded and maintained AWS EKS environments, ensuring compatibility of control plane, node groups, and add-ons with compliance standards and production stability.
- Packaged and deployed Kubernetes applications using Helm charts for consistent, version-controlled releases.
- Enhanced container security by scanning Docker images with Trivy vulnerability scanner before promotion to internal registries, reducing attack surface by 85%.
- Designed a multi-stage CI/CD pipeline (Jenkins) featuring Maven testing (unit → integration), SonarQube analysis, quality gate validation, Docker image build, vulnerability scanning (Trivy), image push to container registry (ECR), and automated deployment to Kubernetes clusters.
- Provisioned AWS infrastructure using Terraform including VPCs, EC2 instances, Security groups, and S3 buckets.
- Managed Terraform state files locally and remotely using S3 backend with DynamoDB locking, preventing concurrent modifications during team development.
- Implemented multi-environment (dev, QA, prod) infrastructure using Terraform workspaces and modular architecture.
- Implemented comprehensive observability with CloudWatch, Prometheus, and Grafana dashboards providing real-time infrastructure and application insights.
- Optimized cloud costs by rightsizing resources, implementing lifecycle policies, and leveraging reserved instances, reducing overall infrastructure spend.
- Optimized Linux server performance (CPU, memory, I/O) using system tuning and monitoring tools, achieving 30% resource utilization improvement.
System Engineer
VMoksha Technologies
- Managed and optimized 5,000+ global Windows, Linux, VMware, and AWS server environments—provisioning 100+ cloud VMs and achieving 99.99% uptime through automation, auto-scaling, and proactive monitoring.
- Led enterprise-wide patch management using SCCM and ManageEngine, ensuring timely security updates, reducing vulnerabilities, and maintaining compliance across servers.
- Provisioned and decommissioned VMs based on client needs while administering VMware ESXi and vCenter across data centers to ensure efficient resource management, scalable provisioning, and high availability.
- Streamlined virtualization operations using VMware by leveraging clones, templates, snapshots, and affinity rules, while configuring HA and DRS to ensure optimal load balancing, automated failover, and high availability.
- Implemented strategies to increase VMware resources, including CPU, memory, storage, and network resources, to improve system performance and accommodate growing workloads.
