Worked on the Metrolist repository to deliver Traditional Chinese localization, focusing on enhancing accessibility and expanding the application's reach for Chinese-speaking users. Leveraged Weblate to manage and track translation progress, increasing UI string coverage from 81.0% to 87.8% within the month. Utilized XML for translation files and applied localization and mobile development skills to ensure accurate and maintainable language support. The workflow established clear traceability through commit history and enabled ongoing updates, supporting future collaboration. This effort laid the foundation for broader internationalization readiness, addressing the need for localized content without introducing new features or fixing existing bugs.
