  • Deployed and configured AWS infrastructure using CloudFormation, Terraform, and Ansible for configuration management. Automated the deployment of developer codes by building CI/CD pipelines using GitHub, Jenkins, Maven, SonarQube, and Nexus to rapidly build, test, and release code while minimizing errors before deployment through Ansible. Monitored our CI/CD pipeline using tools like CloudWatch, IAM, Prometheus & Grafana, and Splunk.
  • Designed and implemented automated SDLC/DevOps pipelines for development, UAT, and production environments using Jenkins Declarative Pipeline and AWS developer tools (CodeCommit, CodePipeline, CodeBuild, CodeArtifact, and CodeDeploy). Established distributed pipeline and built environments with Jenkins Master and Client Architecture and automated operational tasks with AWS Systems Manager, including software inventory collection and OS patch application. Developed event processing architectures for triggering, logging, analysis, visualization, notifications, and remediation
  • Optimize resource levels and manage costs, using Auto Scaling groups for EC2 instances and integrated security and testing tools (DAST, SCA, IAST, and SAST) into pipelines to enhance security and code quality. Implemented AWS security best practices, including multi-factor authentication, access key rotation, role-based permissions, strong password policies, and configuring security groups, NACLs, and S3 policies. Optimized costs through reserved instances, EC2 instance types, S3 storage classes, lifecycle policies, and Auto Scaling. Created Ansible roles and playbooks for deployment and maintenance of software components and managed data lifecycle within S3 buckets to minimize costs based on usage patterns.
