Rockstar🎓
Top SchoolHengqi Chen is a seasoned software engineer with 11 years' experience building serverless infrastructure at Tencent Cloud and deep, practical expertise in eBPF, XDP, and kernel-level tooling. He is an active open-source contributor to high-impact projects such as libbpf, cilium/ebpf, BCC, and libbpf-rs, adding cross-architecture support (including arm64 and LoongArch), new XDP/TC/USDT examples, and kernel-facing API improvements. His work spans Rust, Go, and C, emphasizing robustness, backward/forward kernel compatibility, and performance-sensitive systems programming. Based in Shenzhen, he blends production cloud engineering with low-level systems craftsmanship, and often surfaces non-obvious fixes like BTF loading helpers and auto/manual uprobe attach patterns that improve developer ergonomics.

Scaffolding for BPF application development with libbpf and BPF CO-RE
Role in this project:Back-end Developer
Back-end DeveloperContributions:25 reviews, 13 commits, 11 PRs in 1 year 4 months
Contributions summary:Hengqi primarily contributed to examples related to eBPF applications within the libbpf-bootstrap repository. They added an XDP/Rust example and an example for TC (Traffic Control), showcasing how to utilize libbpf APIs. The user made several changes to adapt the code to libbpf 1.0 mode and incorporated new examples for USDT (User Statically Defined Tracing) and updated the uprobe example with auto-attach and manual attach. The user also added support for arm64 to the examples.
