Worked on the open-ani/animeko repository, focusing on backend development and database reliability. Addressed a critical issue affecting episode collection ordering by refining the SQL logic within the EpisodeCollectionDao, ensuring that sortNumber was prioritized before the sort field in ORDER BY clauses. This fix restored consistent and accurate catalog presentation for users, directly reducing confusion and potential support requests related to misordered episodes. The solution involved careful SQL query debugging and precise changes at the DAO layer, utilizing Kotlin and SQL. All modifications were tracked through Git, demonstrating a methodical approach to maintaining data integrity and user-facing application stability.
