Worked on maintaining the CI/CD infrastructure for the pagopa/pagopa-biz-events-service repository, focusing on ensuring ongoing pipeline reliability amid platform deprecations. Addressed a critical compatibility issue by upgrading the GitHub Actions runner environment from ubuntu-20.04 to ubuntu-22.04, aligning the deployment process with current and future GitHub Actions and Ubuntu support cycles. This update reduced deployment risk and preserved build and test continuity for the project. The work involved hands-on experience with CI/CD pipeline management, GitHub Actions workflow configuration, and Linux system administration, demonstrating a methodical approach to infrastructure maintenance and proactive adaptation to evolving platform requirements.
