Worked on the Metrolist repository to deliver Vietnamese localization and accessibility enhancements, focusing on expanding the app’s reach to Vietnamese-speaking users. Implemented a Weblate-driven translation workflow, localizing UI strings and the automatic sleep timer feature using XML and translation management tools. The approach emphasized internationalization (i18n) best practices and commit-driven development, resulting in measurable progress toward full Vietnamese language support. By reducing localization friction and improving accessibility, the work enabled broader user engagement and laid the groundwork for future internationalization efforts. No major bugs were addressed during this period, with efforts concentrated on feature delivery and workflow optimization.
