Summary
🤩
Rockstar🎓
Top SchoolKeyang Xie is a technical expert with 11 years of hands-on experience designing cloud-native and AI infrastructure, currently driving unified training-inference and high-throughput LLM serving platforms. He combines deep Kubernetes and container runtime expertise with practical ML systems work—building Continuous Batching, PagedAttention optimizations, tensor/expert parallel multi-node inference, and a commercial MaaS marketplace for multimodal models. Previously he led large platform teams at SmartMore and Kingsoft Cloud, shipping Volcano-based GPU scheduling, operator-driven heterogeneous GPU standardization, and Argo-based ML pipelines. An active contributor to open-source serverless and runtime projects (notably improvements and tests for Firecracker and Fission), he brings a quality-first mindset to backend and DevOps engineering. Known for solving systemic performance and stability bottlenecks, he repeatedly translates research-grade methods (LoRA, DeepSpeed ZeRO-3) into production-grade pipelines. Based in Beijing, he pairs an engineering leadership track record with low-level container/runtime fluency that’s rare among ML infrastructure architects.
