Worked on the tier4/scenario_simulator_v2 repository to enhance geographic projection configurability and simulation accuracy. Developed a dynamic map projection configuration system using C++ and YAML, enabling runtime selection between Transverse Mercator and MGRS projections through a modular loader refactored for maintainability and robust error handling. Improved code quality with formatting and header cleanup, and updated unit tests to support the new configuration flow. Additionally, addressed a timing precision issue in the traffic simulation’s behavior control by optimizing the non-acceleration time calculation, ensuring more reliable and reproducible scenario outcomes. Demonstrated strengths in algorithm optimization, configuration management, and simulation engineering.
