Worked on improving database backup reliability in the immich-app/immich repository by addressing compatibility issues with pg_dumpall. Focused on backend development using Node.js and TypeScript, the work involved sanitizing the database connection URL to remove the uselibpqcompat parameter, which previously caused backup failures across different environments. This targeted server-side fix ensured that unknown query parameters would no longer disrupt backup processes, resulting in more stable and consistent database backups. The solution was delivered through a collaborative effort, with careful testing to validate the changes. The work demonstrated attention to cross-environment compatibility and robust backend engineering practices.
