Sebek X developed configurable object filtering margins and LocalCartesian projection support across multiple Autoware repositories, focusing on deployment flexibility and robust geospatial processing. In tier4/autoware_launch and technolojin/autoware.universe, Sebek introduced tunable lanelet margin parameters and enhanced observability through debug visualization and performance timing, enabling more accurate object detection and easier tuning. For autoware.core and autoware.universe, Sebek implemented LocalCartesian projection handling in both core utilities and map loaders, updating C++ code, tests, and documentation to ensure reliable geographic-to-Cartesian transformations. The work demonstrated depth in C++, ROS 2, and configuration management, addressing integration and maintainability in autonomous driving pipelines.
