Worked on the Radarr/Radarr repository to enhance language release parsing by implementing a targeted improvement for German releases. Updated backend C# code to refine regular expressions, enabling accurate identification of GER and DE language tags in release metadata. Developed and integrated dedicated tests to validate German release formats, ensuring robust coverage and preventing future regressions. This focused feature reduced misclassification of German releases, streamlining downstream automation and minimizing manual intervention. Demonstrated backend development skills with an emphasis on regular expressions and test-driven development, contributing to more reliable automation workflows and an improved user experience for language-specific release handling.
