During March 2026, Feliz K. developed an Episode Custom Format and Score Calculation Service for the Sonarr/Sonarr repository, focusing on improving the reliability and automation of the episode import process. Leveraging C#, dependency injection, and robust software design principles, Feliz created a service that analyzes renamed episode filenames to determine and apply appropriate custom formats and scores, including support for language-specific formats. This approach reduced manual intervention and increased consistency in imports by ensuring correct format application. The work demonstrated depth in unit testing and extensibility, laying a foundation for future enhancements within Sonarr’s import pipeline and format handling.
