Worked on the th-ch/youtube-music repository to deliver full Turkish localization for the YouTube Music application, focusing on both UI and workflow integration. Leveraged Weblate to manage and apply translations, achieving 100% coverage of over 450 strings and organizing all updates within the i18n directory. Utilized JSON and i18n best practices to ensure maintainability and scalability of the localization pipeline. The work enhanced accessibility for Turkish-speaking users and established a foundation for future internationalization efforts. No bug fixes were recorded, with efforts concentrated on feature delivery and process improvement, resulting in a robust, market-ready Turkish language experience.
