Senior🎓
Top SchoolZhang Huan is a seasoned filesystem engineer with 15 years of experience designing and hardening distributed storage and metadata systems. Based in Beijing, he led BWFS metadata development and has continued to drive backend and system-level improvements at Beijing Horiscale and the Institute of Computing Technology, CAS. An experienced C developer, his open-source work on GlusterFS includes bug fixes and performance patches—such as replacing mutexes with read-write locks and fixing posix_fsync and XDR return-value bugs—that improved reliability in production-like distributed environments. He combines deep storage research training (Master’s in Computer Science and Storage from ICT, CAS) with hands-on operational experience building diskless-boot snapshot and service-on-demand systems, giving him a pragmatic edge in solving low-level concurrency and correctness issues.
