Worked on the makeplane/plane repository to deliver targeted localization enhancements focused on Vietnamese and Portuguese language support. Implemented precise vi-VN locale handling to ensure accurate translation loading and improved the quality of Portuguese translations, directly addressing content accuracy and user experience for Portuguese-speaking users. The approach involved updating localization assets and maintaining translation consistency using JSON and TypeScript, with a focus on internationalization and localization best practices. These changes reduced friction in the localization process and established a foundation for broader language support, ensuring that user-facing content remains current and accessible to a wider audience across supported regions.
