Over six months, Chumva contributed to OsmAnd’s open-source repositories by developing map rendering features, refining UI elements, and resolving backend integration issues. He enhanced pedestrian navigation in OsmAnd-resources by introducing a dedicated straight walking route line style and improved polygon rendering precision in OsmAnd-core, using Java and XML for configuration and map development. Chumva consolidated AIS icon assets for better maintainability and standardized naming conventions, while also decluttering the UI by hiding less relevant tags. He addressed compile-time errors in OsmAnd-tools, establishing API scaffolding for altitude metrics, and demonstrated strong asset management, backend development, and UI/UX refinement throughout his work.

June 2025: Delivered targeted fixes and UI cleanup across OsmAnd-tools and OsmAnd-resources to bolster reliability and UX. Fixed a compile-time RoutingService integration bug affecting ElevationDiffsCalculator, and cleaned up the Context Menu UI by removing a deprecated gpx_icon option (no code changes). These changes improve elevation accuracy, reduce build friction, and provide a cleaner interface with clear commit traceability.

In May 2025, delivered UI decluttering for OsmAnd-resources by hiding Wikidata tags to declutter the UI and streamline data presentation. Implemented by setting the 'hidden' attribute to true in OsmAnd-resources XML for Wikidata-related tags. This aligns with UX goals to reduce noise and focus on relevant information. The change is tracked under commit 821985ccfdc6cdf865ba802b46f63a480eff83bf.

January 2025 — OsmAnd-core (osmandapp/OsmAnd-core): Focused on enhancing polygon rendering precision for advanced map customization while preserving performance and stability. Key features delivered include Polygons zoom level detail enhancement to support higher-detail rendering for custom polygons. Major bugs fixed include a regression in polygon zoom range that was addressed by constraining the maximum polygon zoom to 21 to prevent rendering issues at very high zooms. All changes are tracked with precise commits to ensure traceability and reproducibility.

December 2024: Delivered a new Straight Walking Route Line Style in OsmAnd-resources by adding a dedicated line style definition for straightWalkingRouteLine. This enhancement improves map readability and pedestrian navigation by visually differentiating straight walking paths from other route types, supporting clearer UX and informed decision-making for users. The change is tracked with commit fdf2ba1f234bac6be2cab93c1f77837a78d0d257 ("Add straightWalkingRouteLine"). No major bugs were reported this month. In addition to delivering the feature, the work demonstrates solid resource management, Git-based collaboration, and styling workflow improvements that reduce maintenance effort and set the foundation for future route-type refinements.
