Worked on the eclipse-sumo/sumo repository to deliver the initial rollout of Hungarian localization across the GUI, Python tools, and user interface strings. Established a scalable internationalization workflow using Weblate, enabling ongoing translation management and transparent progress tracking. Leveraged Python and PO files to integrate new translations, while documenting each milestone with precise commit messaging for traceability. Focused on expanding accessibility for Hungarian-speaking users and laying the groundwork for future localization efforts. The approach emphasized cross-repository coordination and auditability, ensuring that translation progress could be monitored and quality assured throughout the development cycle, with no major bugs reported during this period.
