During December 2024, Erigidissimus focused on backend development for the open-ani/animeko repository, addressing a critical issue affecting episode collection ordering. By analyzing and correcting the SQL query within the EpisodeCollectionDao, Erigidissimus ensured that the sortNumber field was prioritized before the sort field, restoring accurate and stable catalog ordering for users. This fix, implemented in Kotlin and SQL, resolved data integrity concerns and reduced potential user confusion and support requests related to misordered episodes. The work demonstrated careful debugging at the DAO layer and effective use of Git for traceable commits, reflecting a targeted and thoughtful approach to backend maintenance.
