Summary
🤩
Rockstar🎓
Top SchoolNorbert Hu is a systems-oriented software engineer with 11 years of experience building high-performance distributed systems, databases, virtualization, and kernel-level components, currently contributing to Temporal's core service in San Francisco. He has led large-scale infrastructure efforts at Uber—owning Kafka upgrades, durable task queues, large immutable KV stores, and personalized prediction platforms—and previously improved Hyper-V and SQL Server performance at Microsoft. Norbert blends deep low-level expertise (hypervisor bootstrapping, NUMA, shadow page tables) with production-scale backend design and persistence work, often turning prototypes into cross-product performance wins. His open-source contributions to Temporal demonstrate practical mastery of workflow persistence and history management in a widely used orchestration system. Colleagues would note he repeatedly surfaces subtle system bottlenecks and ships pragmatic, scalable fixes rather than theoretical designs.
