Worked on enhancing CI/CD reliability and release automation across the zextras/carbonio-shell-ui and zextras/carbonio-calendars-ui repositories. Upgraded the Jenkins pipeline by updating the jenkins-lib-ui library, ensuring compatibility and maintainability for future releases using Groovy and Jenkins. Later, established an automated release process by migrating to semantic-release, introducing standardized configuration files for ESLint, Renovate, and Prettier to enforce code quality and streamline dependency management in JavaScript projects. Focused on continuous integration and DevOps practices, the work improved release stability and maintainability, laying a foundation for faster, more reliable deployments without introducing new bugs during the development period.
