Top SchoolDavid Liu is a Senior Software Engineer based in Seattle with a decade of experience building high-performance systems for ML, from XLA compiler optimizations to fleet-scale TPU tuning and LLM post-training work at Google/DeepMind. He pairs deep systems expertise—rooted in PhD research on serverless orchestration and lightweight VMs—with practical low-level experience writing Linux kernel drivers for storage servers. At Google he focuses on making GenAI infrastructure fast and reliable, combining compiler-level auto-optimizations with eval pipelines that drive real-world performance gains. His background includes security and privacy work on Android and IoT, giving him a rare cross-domain perspective on trustworthy systems. David’s approach blends research rigor with production-first engineering, and he still enjoys debugging hardware-level quirks—a reminder that he thinks from LED to cloud.
