PROFILE

Jae Ku

Worked on modernizing build systems and improving test stability across major open-source repositories. In pytorch/pytorch, focused on removing platform-specific arguments and compiler flags from the build configuration, enabling migration to Buck2 and unifying cross-platform builds for XNNPACK integration. This reduced configuration drift, improved CI reliability, and accelerated onboarding for new platforms, leveraging skills in Python, C++, and build system management. In facebook/folly, addressed test execution issues by opting out a resource-intensive test from individual automated runs, streamlining CI workflows and reducing resource contention. Demonstrated a methodical approach to software modernization, dependency management, and collaborative cross-repo development.
