Summary
🤩
RockstarAnthony Green is a seasoned Solutions Architect with 27 years of systems-level software experience, currently distinguished at Red Hat. He combines deep expertise in low-level programming, ABIs, and platform support with a track record of designing portable foreign-function interfaces—most notably contributing to and maintaining libffi. Anthony’s work spans CPU architecture ports (including AArch64, moxie, and microblaze), Windows and Solaris platform fixes, and building toolchains like the ocicl Common Lisp distribution, reflecting both breadth and technical depth. Based in Old Toronto, he pairs pragmatic production delivery with inventive side projects—he created the moxie CPU and continues to publish personal "hacks." Colleagues rely on him to solve tricky interoperability and calling-convention problems that other engineers avoid. He blends hands-on development with architectural oversight to make complex, low-level systems robust and portable.

Contributions summary:Anthony appears to have primarily contributed to back-end development tasks within the libffi/libffi repository. Their commits focused on implementing architecture-specific Foreign Function Interface (FFI) support, including for the AArch64, moxie, and microblaze architectures, suggesting an in-depth understanding of system-level programming and ABI details. Furthermore, they also contributed fixes to ABI and struct-related issues, which would suggest experience and knowledge of the underlying internals of the calling conventions. Additional fixes for platform support were made for Windows and Solaris.
