Senior Software Engineer at Alibaba
Beijing, China
Summary
🤩
RockstarPeng Yu is a System Development Engineer with 11 years of experience building and troubleshooting Linux-based infrastructure across x86 and ARM platforms. He has deep hands-on expertise in performance tuning and observability using tools like perf, bcc/ebpf, systemtap, ftrace and tcpdump, and is fluent in C, Rust, Go and Python. At AWS he scaled dataplane services, automated failure handling, and added features to high-throughput systems; he currently applies that operational rigor at Alibaba. His background includes kernel and RHEL maintenance at Red Hat, giving him a rare blend of upstream OS debugging and cloud production experience. Comfortable across container and orchestration stacks (Docker, Kubernetes, etcd) and AWS services (EC2, S3, Lambda), he pairs low-level systems insight with cloud-native delivery. Based in Woodinville, WA, he brings pragmatic troubleshooting instincts and a track record of turning elusive performance problems into stable, measurable outcomes.
