Alisa contributed to the osmandapp/web and OsmAnd-tools repositories by developing robust mapping, navigation, and data management features that improved user workflows and system reliability. She engineered local track management, POI search, and public transport integration, leveraging React, JavaScript, and Java to deliver responsive UI components and efficient backend APIs. Her work included optimizing geospatial data handling, implementing IndexedDB for offline storage, and refining UI/UX for navigation and sharing. Through careful code refactoring, test automation, and internationalization support, Alisa enhanced maintainability and performance, addressing edge cases and ensuring stable releases across complex, data-driven mapping applications used at scale.
In April 2026, delivered focused business-value improvements across mapping, geocoding, Garmin integration, and code quality. Key features include standardizing coordinate precision (BBOX and WEATHER), preparing coordinates for the get-address-by-latlon feature, and introducing a reusable Spinner UI to improve loading UX. Significant refactoring and code-quality work (refacroting and introducing const declarations) improved maintainability and readability. Garmin integration enhancements (new connection buttons, status handling fix, OAuth path correction, and user-visibility gating) reduced user friction and integration risk. A broad set of stability fixes across the test suite, weather forecast handling, and map UI further enhanced reliability and user trust, while minor data-model cleanup and IndexedDB metadata improvements support offline resilience and performance.
