Worked on enhancing the SandMan UI within the sandboxie-plus/Sandboxie repository by updating Chinese and Traditional Chinese localization resources. Focused on improving accessibility and user experience for Chinese-speaking users, the work involved refreshing translation files to align with recent UI changes and ensure comprehensive language coverage. Utilized TypeScript for managing translation files and applied front end development skills to integrate the updates seamlessly. The changes reduced language barriers and facilitated smoother onboarding for users in key markets. This effort established a robust localization workflow, laying the groundwork for future internationalization initiatives and supporting broader usability across diverse user groups.
