Describe your experience with building and maintaining CI/CD pipelines using tools like Jenkins, GitLab CI/CD, or CircleCI

I have extensive experience in building and maintaining CI/CD pipelines using Jenkins and GitLab CI/CD. These tools automate the software delivery process, from code integration and testing to deployment. I've configured pipelines to trigger builds on code commits, run automated tests, and deploy applications to staging and production environments. Continuous monitoring and feedback loops were established to ensure rapid feedback and continuous improvement of the pipelines.
