Worked on expanding German localization for the Metrolist Android application, delivering complete translation coverage across the user interface, song caching, sleep timer, and related features. Leveraged XML for managing translation strings and utilized Weblate to streamline the localization workflow, ensuring all 701 German strings were accurately integrated and tracked through three commits. Focused on internationalization and mobile development best practices, the work improved the user experience for German-speaking users and reduced localization-related support needs. Documented translation progress within commit messages and aligned updates with continuous integration checks, enhancing readiness for future language support in the Metrolist repository.
