Worked on enhancing Indonesian localization and accessibility for the OsmAnd-iOS and OsmAnd repositories, focusing on expanding translation coverage and improving user experience for Indonesian-speaking users. Leveraged Swift and XML to add new translations, correct existing strings, and introduce accessibility-focused updates such as the 'liter_single' string. Utilized Weblate-driven workflows to streamline translation management and ensure scalable, contributor-friendly updates across both projects. The work resulted in increased translation coverage, with OsmAnd-iOS reaching 94.5% and OsmAnd achieving 97.7%. These improvements supported better onboarding and retention for Indonesian users by delivering higher quality localization and more accessible application interfaces.
