Worked on YerongAI/Office-Tool to enhance localization and usability for Vietnamese users by updating language resources and refining keyboard shortcuts throughout the application. Focused on internationalization and localization, the work involved managing resource files using XAML and XML to ensure accurate translations and improved user experience. No major bugs were addressed during this period, as the primary goal was to strengthen the application's readiness for broader language support and streamline workflows for Vietnamese speakers. The approach emphasized resource management and accessibility, resulting in a more intuitive interface and laying the groundwork for future internationalization efforts within the repository.
