Explain the concept of CI/CD (Continuous Integration/Continuous Deployment) and how it is implemented in your previous projects.

Continuous Integration (CI) and Continuous Deployment (CD) are essential practices in modern software development. CI involves frequently integrating code changes into a shared repository, ensuring that all changes are tested and validated through automated builds and tests. CD extends CI by automatically deploying code to production or staging environments after passing automated tests. In my previous projects, we achieved CI/CD by utilizing tools like Jenkins and GitLab CI. Whenever a developer pushed code changes, automated tests were triggered. If the tests passed, the code was automatically deployed to staging servers. After further testing in the staging environment, it was deployed to production.
