Worked on stabilizing the inspector module within the Tencent/tgfx repository by addressing a critical build issue in C++. Focused on header hygiene, the developer identified and resolved a missing <cstddef> header in ProcessUtils.cpp, which had caused compile-time errors and disrupted the build process. By implementing this targeted fix, they improved build reliability and reduced triage time for related changes, directly benefiting developer velocity and CI efficiency. The work demonstrated careful attention to C++ header management and precise change traceability, with all updates delivered through clear, collaborative commits. No new features were added, but essential maintenance was effectively prioritized.
