Summary
🤩
Rockstar🎓
Top SchoolY Guo is a software engineer with 12 years of experience building production-grade networking and backend systems, currently contributing to Onehouse from Mountain View. With a PhD in Computer Science from the University of Michigan, his work bridges academic research in mobile and datacenter networking—published at SIGCOMM, MobiCom, and IMC—with hands-on engineering at Uber and contributions to Apache Hudi’s core engine. He focuses on moving the needle: improving QoE, energy efficiency, and robustness of multipath and mobile networking stacks at scale. Equally comfortable in research and product environments, he has operationalized ideas like on-device bufferbloat mitigation and partial-update handling in big data systems. An Apache Hudi PMC-affiliated contributor, he combines protocol-level insight with pragmatic backend optimizations that directly impact production infrastructure.
