PROFILE

Peiyang He

Worked on the google/syzkaller and slatedb repositories, focusing on Linux kernel development, device driver improvements, and documentation. Enhanced memory management reliability by implementing specialized munmap mappings for subsystems such as bifrost, binder, kvm, and io_uring, reducing false positives in fuzzing and improving test coverage. Improved the UInput API by aligning syzlang descriptions with the actual UAPI and correcting ioctl handling. In slatedb, updated simulation documentation to clarify the use of a SQLite-backed database copy, streamlining onboarding and reducing misconfigurations. Utilized Rust and C, emphasizing maintainability, accurate documentation, and robust system programming practices throughout the development process.
