During May 2026, Roongroj focused on enhancing the affaan-m/ECC repository by implementing Thai language support across project documentation. He translated the main README into Thai using Markdown and updated language switchers throughout multiple README files to include direct links to the new Thai page. This approach improved accessibility and navigation for Thai-speaking users, laying a foundation for scalable internationalization and localization. Roongroj concentrated on documentation quality and user experience consistency, rather than bug fixes, ensuring that multilingual support is both discoverable and maintainable. His work demonstrated depth in documentation, internationalization, and localization, addressing global onboarding challenges for the project.
