Worked on the nordic-institute/X-Road repository to implement Russian language support throughout the application, focusing on both internationalization and the admin user interface. The approach involved updating two i18n configuration files and two service UI configurations, enabling Russian as a selectable language and integrating it into admin workflows. All changes were delivered in two well-documented commits to ensure traceability and minimize risk. Utilizing JavaScript and TypeScript, the work expanded localization coverage and aligned with the broader localization strategy. This addition allows Russian-speaking users to access the platform more effectively and improves usability for administrators managing multilingual environments.
