Summary
🤩
Rockstar🎓
Top SchoolJiaxun Yang is a research-focused electronics and computer science engineer with 11 years of hands-on experience spanning OS, embedded systems, VLSI and distributed ML for edge and 5G RAN. Currently a Research Assistant at the University of Edinburgh and a founding Ecosystem Engineer at a RISC IP startup, he bridges silicon, firmware and system software—contributing upstream to projects like the Linux kernel, QEMU and the widely used OpenBLAS. His low-level work includes performance optimizations for MIPS64/Alpha in OpenBLAS and power-management control for Ryzen APUs, reflecting deep familiarity with architecture-specific assembly, build systems and platform bring-up. A licensed amateur radio operator and private pilot, he blends practical RF and avionics experience with academic study (MPhil, Cambridge) and FPGA/heterogeneous acceleration research, making him equally comfortable in labs, skies and open-source communities.
