Summary
🤩
Rockstar🎓
Top SchoolJonathan Kunkee is a software engineer with a decade of experience building low-level systems and cross-platform build infrastructure, currently working at Microsoft on kernel APIs and x86-on-ARM64 emulation. He has deep expertise in Windows build systems and ARM64 support—evident from contributions to high-profile projects like Node.js, libvpx, and the OpenVPN TAP driver where he enabled ARM64 Windows builds and modernized EWDK-based automation. Jonathan combines embedded systems know-how from SpotterRF with practical driver and toolchain experience, making him comfortable across kernel, firmware, and userland boundaries. He’s pragmatic about compatibility quirks (for example, addressing ARM64 Windows SDK issues) and skilled at turning brittle build processes into reproducible releases.
