PROFILE
Piotr Zyskowski
Piotr Zyskowski enhanced the tier4/scenario_simulator_v2 repository by developing a dynamic map projection configuration system, enabling runtime selection between Transverse Mercator and MGRS projections through YAML-based configuration. He refactored the projection loader for modularity and improved error handling, which reduced setup errors and increased maintainability. Using C++ and CMake, Piotr also extracted reusable components for projection logic and updated unit tests to support the new configuration flow. Additionally, he addressed a timing precision issue in the traffic behavior controller, optimizing non-acceleration time calculations to improve simulation fidelity. His work demonstrated depth in algorithm optimization and configuration management.
