Summary

With over 8 years of experience in AWS DevOps, I have designed and built applications using various AWS services like EC2, CloudWatch, S3, Elastic Beanstalk, ELB, Auto Scaling, RDS, VPC, Route53, and IAM. I have expertise in DevOps tools such as Jenkins, Nexus, Chef, and Ansible for building and deploying applications. I have managed servers on AWS using Chef Configuration management and Ansible for infrastructure automation. I have worked with container systems like Docker, Docker Swarm, Kubernetes, and OpenShift. I have experience with Kubernetes architecture, troubleshooting, and multi-regional deployment models. I have integrated infrastructure automation using Puppet and created Jenkins jobs, build, and delivery pipelines. I have extensive experience with MAVEN and ANT for building deployable artifacts and automating build processes using Jenkins and Groovy scripts. I have proficiency in scripting languages like Shell, Ruby, and Python, focusing on DevOps tools, CI/CD, and AWS Cloud Architecture.
