Rockstar

Yusheng Zheng is a systems-focused software engineer and PhD student at UC Santa Cruz with seven years’ experience building open-source tooling around eBPF, kernel tracing, and runtime systems. He founded eunomia-bpf (eunomia.dev), the popular eBPF project with 5k+ stars, and has led development of BPF programs, userspace runtimes (DPDK/XDP), and toolchains while mentoring small teams. His background spans OS-level work—including adding syscalls and documenting a Rust microkernel—and static analysis tooling using Clang/Infer, showing a mix of low-level systems engineering and developer ergonomics. Based in London and originally trained in Geographic Information Science at Zhejiang University, he combines academic research rigor with hands-on open-source product building. Notably, he pairs deep kernel-level expertise with a playful, curious open-source persona that fuels practical, well-documented projects.

eBPF Developer Tutorial: Learning eBPF Step by Step with Examples

Role in this project:

Back-end Developer & Systems Programmer

Contributions:45 reviews, 35 commits, 108 PRs in 3 months

Contributions summary:云微 primarily contributed to the development of BPF (Berkeley Packet Filter) programs within the repository. Their work involved implementing and modifying various BPF programs for tracing system events, including hard interrupt handling, process execution, signal handling, and system calls like `open` and `execve`. The user also added and updated header files and maps, demonstrating a strong understanding of eBPF and kernel-level programming.
