   I am a DevOps and Cloud Infrastructure Archtect with expertise in automating, scaling, and securing environments across AWS, Kubernetes, and CI/CD platforms. My focus is on delivering highly available, fault-tolerant, and compliant solutions that improve software delivery and operational efficiency.I have hands-on experience configuring AWS services (EC2, S3, RDS, EBS, ELB, Route53, DynamoDB, IAM, CloudWatch, SNS) using Terraform to implement Infrastructure as Code. I have designed and deployed applications leveraging the AWS stack with strong emphasis on auto-scaling, resilience, and cost optimization.In CI/CD, I transitioned pipelines from Jenkins to GitHub Actions, reducing build times and streamlining releases. I also integrated GitHub Enterprise with Jira, Confluence, and Jenkins, creating a unified development ecosystem. By automating workflows with Python and Bash scripts, I improved deployment frequency and reliability while reducing manual tasks.On the containerization side, I designed microservices architectures using AWS ECS Fargate and Docker, implementing blue-green and rolling deployments to minimize downtime. I developed and deployed custom Docker images to ensure efficient performance and integrated AWS CodePipeline, Jenkins, and Git for end-to-end automation.I have also provisioned Kubernetes clusters with Kops and Kubeadm, configuring masters, worker nodes, networking, and service discovery. By integrating Kubernetes with Jenkins pipelines, I enabled automated rollouts and rolling updates triggered after successful builds.To ensure reliability, I use CloudWatch for monitoring and alarms, with SNS for real-time alerts. I maintain reusable Terraform codebases and leverage platforms like Scalar to streamline deployments.With strong expertise in cloud automation, CI/CD, and container orchestration, I deliver scalable, secure, and reliable solutions that drive business success.Created & deployed micro services on Azure AKS Clusters & App Services.
