Worked on advancing German localization for the Metrolist app, focusing on expanding translation coverage across core user interface strings, sleep timer features, and playlist export messaging. Leveraged XML and Android development skills to integrate new translations, using Weblate to manage and streamline the localization workflow. Prioritized internationalization and accessibility, aligning translated strings with user-facing flows to support broader adoption among German-speaking users. No bugs were addressed during this period, as the primary goal was to increase translation completeness, reaching 81% coverage. Established ongoing quality assurance practices to ensure consistency and set the stage for future localization and UX improvements.
