Summary
🤩
RockstarWei Liu is a Principal Software Engineering Manager at Microsoft with 15 years of experience building virtualization and cloud-native stacks, leading the team that owns Cloud Hypervisor and the Linux kernel components used for AKS isolated containers. An open-source systems engineer and long-time Xen contributor, he maintains the upstream Linux on Hyper-V tree, sits on the Cloud Hypervisor architecture committee, and has hands-on work across unikernels (Rumprun) and Rust-based VMMs. He blends management and architecture leadership with deep kernel-and-hypervisor coding — from hypercall and event-channel fixes to memory and vCPU refactors — and previously drove major Xen platform development at Citrix. With a Master’s in Information Security and an early research background building shellcode transformation tools, he brings a security-minded, hacker-curious approach to production virtualization systems.
