During March 2025, Diego Geler contributed to the OpenRailAssociation/osrd repository by implementing German language localization support for the front end. He updated the internationalization configuration to add German as both a supported and fallback language, establishing a foundation for future German content and broader accessibility. Using JavaScript and TypeScript, Diego focused on front-end development and internationalization workflows, ensuring that the localization scaffolding aligned with the project’s roadmap. His work prepared the application for staged German content rollout, reducing future integration efforts and supporting traceability through targeted git commits. No major bugs were addressed during this period, reflecting focused feature delivery.
