Worked on expanding Vietnamese language support in the luanti-org/luanti repository by delivering localization enhancements across the user interface and settings. Utilized PO files and Weblate to translate and integrate 44.9% of the application’s strings, laying the foundation for ongoing localization cycles. Focused on improving accessibility for Vietnamese-speaking users, the work included establishing a translation workflow and documenting progress for future audits. Applied skills in localization, software development, and translation to ensure that the application’s core UI became more accessible, thereby increasing market readiness and user satisfaction without introducing new bug fixes during the documented period.
