Rockstar🎓
Top SchoolSacha Refshauge is a Head of AI and seasoned software engineer with 16 years of experience building high-performance C++ systems, machine learning pipelines, and embedded camera solutions from Brisbane, Australia. He combines deep systems expertise (Linux, Qt, CUDA, AVX/NEON, OneDNN) with practical ML productization—leading teams to deliver low-latency, compact facial analytics models that ranked highly in NIST evaluations. As an engineer he’s refactored and modernized complex, legacy codebases (notably contributing UI and architecture work to prominent emulation projects like PCSX2 and RPCS3) and improved cross-platform build and CI tooling across OpenBLAS and Hunter. He’s comfortable at the intersection of research and production, holding advanced degrees from QUT including PhD work in augmented reality while shipping optimized inference libraries and SDKs. Colleagues know him for pragmatic optimizations that squeeze performance out of constrained hardware and for making maintainability a first-class concern in long-lived systems. Now leading AI at Xailient, he focuses on turning research-grade models into deployed, hardware-aware solutions.

Role in this project:Back-end Developer
Back-end DeveloperContributions:52 commits, 74 PRs, 258 comments in 2 years 2 months
Contributions summary:Sacha primarily contributed to the `ruslo/hunter` repository by adding and updating package definitions for the Hunter build system, which is designed for dependency management. Their work involved adding new versions of libraries like libxml2, OpenCV, dlib, PostgreSQL, Jpeg, ONNX, and FP16, as well as updating existing ones. These updates involved modifying build scripts (cmake files), configuration files, and example files to ensure the correct integration and functionality of the libraries within the Hunter build system.
