Worked on the OpenRailAssociation/osrd repository to deliver initial German language localization support for the front end, focusing on updating the internationalization configuration to include German as both a supported and fallback language. This effort established the necessary scaffolding for future German content, enabling broader accessibility and preparing the product for staged content rollout. The work involved front-end development using JavaScript and TypeScript, with careful attention to localization workflows and git-based traceability. No major bugs were addressed during this period, as the primary focus was on laying a robust foundation for internationalization and reducing future integration complexity for German-speaking users.
