Worked on backend development for the jxxghp/MoviePilot repository, focusing on stabilizing and improving the accuracy of resource category filtering. Addressed a core issue where category filters could be misapplied during resource browsing by ensuring category IDs are properly parsed and split before comparison. This Python-based solution enhanced the reliability of category application, resulting in more accurate search results and a smoother user experience. The work involved careful debugging and targeted code changes, maintaining code quality while minimizing deployment risk. No new features were introduced during this period, with efforts concentrated on resolving this critical bug and refining backend logic.
