Rockstar🎓
Top SchoolJiang Liu is a senior software engineer based in Beijing with 14 years of deep systems and kernel expertise across Linux, OpenSolaris and cloud microVM projects. He is a prolific upstream contributor—over 200 Linux kernel patches in the past year and more than 30K lines to OpenSolaris—specializing in Intel x86 architecture, PCI, ACPI, memory management and device drivers. At companies including Intel, Huawei and Alibaba Cloud he led work on CPU/memory hotplug, IOMMU drivers and hardware error handling, and now contributes to high-profile open-source projects like Firecracker and Kata Containers to harden memory validation and VirtIO device state handling. Comfortable in both C and Rust ecosystems, he focuses on reliability, spec-compliance and pragmatic refactors that improve maintainability. Colleagues rely on him for solving low-level, hard-to-reproduce issues where hardware, firmware and OS interact.
