Rockstar🎓
Top SchoolAndrew Clayton is a seasoned C software engineer with 18 years of experience and a 25+-year Linux user history, currently working on the open-source NGINX Unit project at F5. He brings deep systems-level expertise from long-term contributions to the Linux kernel, VLC, libdvdread and a range of networking and infrastructure projects, and prefers a minimalist Linux toolchain with vim, gcc, gdb and git. Andrew’s recent Unit work focused on hardening and performance—bug fixes, safer signal handling to prevent segfaults, and code-quality improvements that aid compiler optimization and static analysis. As a former self-employed C developer and systems administrator, he combines pragmatic production experience with ongoing open-source stewardship visible on github.com/ac000. Based in Milnathort, Scotland, he’s an engineer who quietly improves robustness and clarity in complex, low-level codebases.
