During December 2024, this developer contributed to the Tencent/ncnn repository by removing Windows ARM32 build support, focusing on streamlining the Windows build pipeline and reducing long-term maintenance overhead. Using CMake and Python scripting, they eliminated ARM32-specific configurations and directories, which simplified the continuous integration matrix and improved build stability for Windows targets. The work was carefully documented and traceable through an explicit commit reference, supporting future audits and code reviews. By narrowing the supported architectures, the developer enabled faster release cycles and more maintainable builds, demonstrating a thoughtful approach to technical debt and cross-platform build management.
