PROFILE
Ayappan Perumal
Worked on cross-platform build and runtime reliability for major open-source projects, including python/cpython, picnixz/cpython, and ROCm/onnxruntime. Focused on resolving platform-specific issues by adjusting build system configuration and CMake scripts, such as modifying linker flags for AIX and gating Linux-specific API checks to prevent failures on non-Linux systems. Improved subprocess file descriptor handling in C for AIX and enhanced documentation practices by ensuring accurate release note categorization. Addressed symbol export consistency in C++ for ONNX Runtime on AIX, using CMake and Python scripting to align platform behavior. Prioritized CI stability, release hygiene, and multi-OS compatibility throughout.

Oct 1, 2025October 2025: Delivered a cross-platform build stability improvement for picnixz/cpython by gating the statx availability check to Linux builds. This prevents Linux-specific API checks from affecting non-Linux environments, reducing build failures and CI noise, and accelerating release readiness. Change recorded as gh-140239: 'Check statx availability only on Linux (#140249)' with commit 92025ea2c8a10aa0e3dd5a2a1548f9bb17fe7dbc.
