Designed and implemented enterprise-grade DevOps solutions for insurance applications. Maintained AWS infrastructure across VPC, EC2, EKS, S3, RDS, Lambda, IAM, CloudWatch/CloudTrail, Route 53, ALB, WAF, KMS, Secrets Manager, and automation via Terraform. Built end-to-end CI/CD pipelines using Jenkins, GitHub Actions, Maven, Docker, and Kubernetes to automate build, test, security validation, and deployment workflows. Containerized Java applications and integrated vulnerability scanning and publishing to container registries. Integrated SonarQube and Snyk in CI/CD, configured centralized logging, and supported audit requirements with CloudTrail and secure deployment practices. Managed production EKS operations including ingress/controllers, resource tuning, HPA, rolling deployments, and troubleshooting for networking, DNS, IAM, and application/database connectivity. Worked with Ansible playbooks integrated with Terraform using DynamoDB state locking.

Worked on AWS and Kubernetes platforms including EC2, VPC, S3, AMI, SNS, RDS, CloudWatch, Auto Scaling, CloudFront, IAM, and S3. Built AWS CloudFormation templates for VPC, subnets, and NAT to enable web and database deployments. Managed CI/CD using Jenkins to build, test, and deploy containerized microservices to DEV/UAT/PROD Kubernetes clusters, leveraging Ansible and Helm for reproducible builds and releases. Set up Prometheus, Alertmanager, and Grafana dashboards for EKS observability; developed monitoring approaches and alerting. Created Ansible playbooks for automation tasks such as file copy, permissions, configuration changes, folder creation, and orchestration/deployment automation. Integrated Jenkins with Nexus and SonarQube and supported secure automation practices. Implemented Terraform-based infrastructure automation to reduce manual work and errors. Contributed to microservices migration and automation workflows, and supported identity/access control using Active Director

Worked on AWS cloud platform capabilities including EC2, VPC, S3, AMI, SNS, RDS, CloudWatch, Auto Scaling, CloudFront, IAM, and S3 configuration. Created AWS CloudFormation templates to deploy VPCs/subnets/NAT for web and database workloads. Managed CI/CD with Jenkins for building, testing, and deploying containerized microservices on Kubernetes using Ansible across DEV/UAT/PROD. Managed Kubernetes charts via Helm and release packaging. Implemented Prometheus and Alertmanager on EKS, and created Grafana dashboards for health monitoring. Developed Ansible playbooks for automation tasks and integrated Jenkins with Nexus, SonarQube, and Ansible in a containerized CI runtime. Advanced security and reliability practices using monitoring tools (Splunk/Datadog/Grafana), Prometheus/Grafana, and streamlined automation for infrastructure deployment and configuration with Terraform. Also supported Active Directory security/access controls and LDAP integration; contributed to migrations toward mic
