Worked on the th-ch/youtube-music repository to deliver complete Spanish user interface translations, focusing on both internationalization and accessibility. Leveraged JSON and Weblate to automate and streamline the translation process, achieving full coverage of 463 UI strings. Enhanced the accessibility of the application for Spanish-speaking users by translating key interface elements such as HTTPS settings and status display types, improving overall usability. Established a workflow that enables rapid updates for Spanish and supports future language expansions. The work demonstrated proficiency in front end development, i18n, and localization, with an emphasis on maintainable, scalable translation practices and user-centered design.
