Worked on enhancing the stability and reliability of the pfperl-api component within the inverse-inc/packetfence repository, focusing on backend development and system administration using Perl. Addressed a critical issue where the pfperl-api manager could exit unexpectedly if a worker process terminated, implementing a targeted fix to ensure continuous operation. Improved the startup sequence by ensuring proper initialization of application and logging modules, which strengthened observability and troubleshooting capabilities. These changes reduced the risk of unplanned downtime and improved maintainability, aligning with production reliability goals. The work demonstrated a methodical approach to risk reduction and operational resilience in backend API services.
