DevOps Engineer
VSP
May 2020 - Present
- As a Cloud DevOps Engineer, I worked on the migration of applications to the AWS cloud by architecting and implementing CI/CD pipelines using Jenkins. Key contributions to the project include: • Establishment of CI/CD pipelines tailored for Microservices, integrating essential tools like Maven, Bitbucket, SonarQube, Nexus, Docker, and Slack to provide immediate feedback to development teams post-code check-in. • Provisioning of dynamic Jenkins Docker slaves using Docker Host to support efficient CI/CD workflows. • Development of Ansible playbooks from scratch in YAML, encompassing installation, setup, and troubleshooting, while automating platform environment configuration. • Configuration of Git repositories and SSH Keys in GitHub to support Agile teams' version control requirements. • Integration of GitHub webhooks into Jenkins to automate the code check-out process, enhancing workflow automation. • Implementation of master-slave architecture within Jenkins to optimize performance and scalability. • Migration of existing infrastructure into Terraform using the Terraform Import command. • Creation of Docker files and automation of Docker image creation using Jenkins and Docker, streamlining deployment processes. • Automation of infrastructure provisioning on AWS using Terraform and Ansible, enhancing deployment agility. • Establishment of nightly builds integrated with code quality tools such as SonarQube and Veracode, ensuring continuous quality assurance. • Implementation of quality gates in SonarQube dashboards, seamlessly integrated into CI/CD pipelines to maintain building integrity. • Rebuilding the entire existing platform to Docker containers, enhancing portability and resource efficiency. • Setup of Kubernetes clusters using Amazon EKS to optimize containerized application orchestration and management on AWS infrastructure.
