Worked on the th-ch/youtube-music repository to deliver full Portuguese (Brazil) localization, achieving 100% translation coverage for 456 strings using JSON and the Weblate translation platform. Focused on improving accessibility and user experience for PT-BR speakers, the work involved integrating translations directly into the application and establishing a streamlined internationalization workflow. Demonstrated skills in i18n, localization, and translation management, with careful documentation of commits and progress to ensure traceability for future releases. The approach emphasized commit-driven development and centralized i18n tracking, expanding the app’s audience reach and enhancing localization fidelity without addressing major bug fixes during this period.
