Worked on stabilizing the data layer for the LMS-Community/slimserver repository, focusing on backend reliability and database management using Perl. Addressed a persistent issue with SQLite by refactoring the database connection lifecycle, specifically moving the persist.db attachment to the postConnect phase. This adjustment prevented errors from repeated on_connect_do calls and resolved conflicts where the persistent database was already in use. The solution resulted in a more resilient backend, reducing runtime errors and lowering downtime. By improving the predictability of persistence-related deployments, the work enabled smoother production releases and decreased the frequency of support incidents related to database operations.
