During November 2024, Brianna Richardson upgraded the Esri/arcgis-maps-sdk-toolkit-qt repository to ArcGIS Runtime SDK 200.6.0, modernizing the build system with CMake and migrating components from QML to improve maintainability and compatibility. She also reorganized and cleaned up the Esri/arcgis-maps-sdk-samples-qt repository, standardizing licensing and addressing build issues. When stability concerns arose, she executed targeted rollbacks and version reversions, restoring prior configurations and ensuring consistent behavior across samples. Her work demonstrated strong proficiency in C++, CMake, and the Qt framework, balancing the adoption of new SDK features with careful attention to software stability and developer experience.
