During December 2025, Alex contributed to the marcocorvi/topodroid repository by developing and releasing a feature that enables direct sharing of KML and Therion export files within the Android application. He enhanced the export dialogs with new UI elements and implemented backend sharing logic in Java, introducing a generic shareFile method and integrating it into the SaveDataFileTask workflow. Alex also extended application settings to support sharing preferences and added error handling resources for failed shares. This work streamlined the export process, reducing manual steps for users and improving collaboration, demonstrating depth in Android development, file handling, and UI design.
