Worked on the th-ch/youtube-music repository to enhance localization by delivering Estonian translations for user interface strings, error messages, and menu options. Focused on internationalization, the developer established a Weblate-based translation management workflow, enabling ongoing updates and collaboration for multilingual support. Using JSON for translation resources, the work covered 33.3% of the required strings, laying the foundation for improved accessibility for Estonian-speaking users. The approach emphasized structured translation management and integration with existing development processes, supporting broader market reach. Skills applied included i18n, localization, and translation management, with all changes tracked and linked for transparent progress and future contributions.
