Summary
👤
Senior🎓
Top SchoolLeo Yan is a seasoned software engineer with 11 years of deep expertise in ARM architecture, Linux kernel internals and performance tooling, currently contributing at Arm in Cambridge. He brings strong C and assembly skills, hands-on experience with Arm CoreSight, SPE, TF-A and PMU/Perf development, and a track record of enabling power management and PSCI on real SoCs. At Linaro and in contributions to the widely used ARM Trusted Firmware project he worked on HiKey platforms, CPU topology, suspend/resume hooks and hardware debug quirks—practical work that bridges upstream open-source and board-level bring-up. His background includes developing TrustZone frameworks and in-kernel CPU switching at Marvell, reflecting a rare combination of low-level firmware, kernel and systems performance tuning. Colleagues rely on him for technical training and day-to-day support on power, kernel and debug topics, and he often surfaces subtle hardware-software interactions before they become production issues.
