During November 2024, Brian 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. He also reorganized and cleaned up the Esri/arcgis-maps-sdk-samples-qt repository, standardizing licensing and addressing build issues. When stability concerns arose, Brian executed targeted rollbacks and version reversions, restoring prior configurations and ensuring consistent runtime behavior. His work demonstrated depth in C++ development, build system configuration, and SDK integration, balancing the adoption of new technologies with careful attention to stability and long-term maintainability across both repositories.
