Rockstar🎓
Top SchoolChunyang Hui is a software engineer with 10 years' experience specializing in storage acceleration and data center security, currently at Ant Financial after a tenure at Intel where he worked on SPDK and ISA-L. He is an active open-source contributor to high-impact projects like spdk/spdk and occlum, adding NVMe security features, Opal support, AIO enhancements, and SGX simulation fixes that touch both low-level assembly and system-call handling. Comfortable across embedded systems and cloud-scale storage stacks, Chunyang blends protocol-level expertise with pragmatic engineering to improve I/O performance and robustness. Based in Shanghai, he pairs an MS in Electrical and Computer Engineering with hands-on experience shipping security-sensitive storage features used in production environments. An uncommon strength is his ability to navigate between assembly-level fixes and higher-level storage performance optimizations, making him effective at bridging hardware-software gaps.

occlum/occlum
Feb 2020 - Jan 2023
Occlum is a memory-safe, multi-process library OS for Intel SGX
Role in this project:
Back-end & Security Engineer
Back-end & Security EngineerContributions:183 reviews, 390 commits, 256 PRs in 2 years 11 months
Contributions summary:Chunyang focused on enhancing the security and functionality of the Occlum OS, specifically in its SGX simulation mode. Contributions involved implementing support for SGX simulation mode, which included modifications to the underlying x86-64 assembly code to use arch_prctl instead of RDFSBASE/WRFSBASE, and resolving debugging issues. Furthermore, the user addressed and fixed errors in the test suite related to the handling of system calls, notably for the exit_group syscall in simulation mode. These changes improved the simulator's robustness and developer experience.

Storage Performance Development Kit
Role in this project:Back-end Developer
Back-end DeveloperContributions:57 commits, 50 comments, 6 issues in 2 years 3 months
Contributions summary:Chunyang primarily contributed to the `bdev/aio` component, adding support for a configuration retrieval function and making adjustments to AIO-related functionalities. They introduced and implemented features related to the `bdev/iscsi` and `bdevperf` components, including adding the ability to flush, unmap, and reset blocks. These changes indicate a focus on storage performance and I/O operations within the SPDK project. Further contributions to the NVMe subsystem, including security send/receive operations, and Opal support, suggest expertise in low-level storage protocols.
