Worked on expanding accessibility in the iOfficeAI/AionUi repository by delivering Russian localization for the user interface. Focused on front end development, the work involved localizing UI elements and updating the i18n configuration baseline to support the new Russian locale. Using TypeScript and JSON, the developer synchronized the i18n baseline with upstream changes, ensuring consistency across language support. The implementation included formatting updates to the configuration, enabling easier future locale expansions. This contribution addressed the need for Russian-speaking users to interact with the application in their native language, enhancing usability and laying groundwork for broader internationalization and localization efforts.
