Daisuke Nishimatsu delivered targeted platform and build system enhancements across two repositories over a two-month period. For conda-forge-pinning-feedstock, he added ARM64 support for Livox SDK2, updating architecture-specific build lists to enable seamless compilation on Linux and macOS ARM systems, which improved accessibility for ARM-based development workflows. In tier4/scenario_simulator_v2, he migrated the simulation interface to ZeroMQ using cppzmq, integrated the new messaging library with CMake, and refined code formatting and spell checking configurations. Working primarily in C++ and CMake, Daisuke focused on cross-platform compatibility, build reliability, and maintainability, demonstrating depth in system programming and configuration management.
