Top SchoolFred Emmott is an experienced software engineer and consultant with 18 years building reliable systems, tooling, and open-source software, now focused on VR and OpenXR for aeronautic, military, and recreational simulators. He has a long history at Facebook and Slack working on runtime engineering (HHVM/Hack), build systems, tooling and SRE-style automation, and he’s an invited expert member of the Khronos Group OpenXR working group. A prolific open-source contributor, his patches span major projects like Composer, Folly, Flow, HHVM and PHPUnit—often solving portability, build, and compatibility challenges across languages and platforms. Equally at home in backend code and DevOps, he has repeatedly modernized build pipelines and cross-platform CI, including macOS and older Linux distributions. Based in Austin, he combines deep systems knowledge with practical product-minded engineering, and uniquely bridges low-level runtime issues with high-level VR platform design.
