During a two-month period, Steven Loretz focused on build system reliability and dependency management within the autowarefoundation/autoware.core repository. He improved build configuration by migrating GeographicLib discovery to a CMake Find module and resolved compatibility issues in the trajectory module by updating pybind11 linking and tf2 headers. Steven also addressed missing dependencies in localization utility tests, ensuring consistent builds and test execution. In a later phase, he fixed YAML-CPP linking for autoware_test_utils, enabling robust YAML support in test tooling. His work demonstrated depth in C++, CMake, and ROS, emphasizing maintainable build systems and stable continuous integration pipelines.
