PROFILE
Hiroaki Nakamura
Over six months, contributed to apache/trafficserver by delivering seven features and resolving four bugs, focusing on core stability, performance, and maintainability. Work included modernizing string handling in C++ using std::string_view, refactoring APIs for safer memory management, and improving build reliability across environments. Addressed memory leaks and enhanced resource lifecycle in plugins and logging subsystems, while also streamlining HTTP/3 and Rust-based dependency builds through Dockerfile and CMake updates. Leveraged skills in C++, CMake, and Rust to reduce technical debt, improve test reliability, and enable smoother deployments, resulting in a more robust and maintainable codebase for long-term project health.
