Worked on the alibaba/MNN repository to address critical reliability issues in both ARM64 CPU feature detection and iOS framework delivery. Applied expertise in ARM architecture and system programming to correct i8mm runtime detection by switching to AT_HWCAP2, ensuring accurate CPU capability checks and enabling proper optimizations for supported devices. Later, focused on build system configuration and iOS development by refining the CMake-based packaging pipeline, aligning version strings, and removing explicit Info.plist dependencies. These targeted C++ and CMake fixes resolved persistent install-time errors, improved CI reliability, and enhanced the developer experience for iOS users integrating the MNN framework.

Jan 1, 2025January 2025: In alibaba/MNN, delivered a targeted ARM64 i8mm CPU feature detection bug fix to ensure correct runtime feature queries and enable proper optimizations. By switching the detection to AT_HWCAP2, the CPURuntime now reliably recognizes i8mm support, reducing misrouting and improving performance on supported devices. Commit: c0e14f23244834e540d435a3e39fb5331767461d.
