Arina worked on establishing Russian localization for the Eclipse SUMO suite, focusing on improving accessibility for Russian-speaking users. She implemented initial translations using Weblate, covering components such as the GUI, Netedit, and Python tools within the eclipse-sumo/sumo repository. Her approach involved setting up a scalable localization workflow, integrating PO file management and Git-based change tracking to support ongoing translation contributions. By collaborating with translation teams and leveraging her skills in Python, localization, and software development, Arina laid the foundation for broader internationalization, although the depth of translation coverage remained limited during this initial phase of the project.
