Wai Wu is a software engineer in San Francisco with three years of hands-on experience spanning big tech and early-stage startups, currently on the core team at Databricks Mosaic Research building infrastructure to train and serve state-of-the-art LLMs on thousands of NVIDIA H100s. He has deep production experience in high-scale data ingestion and ETL systems from early roles at Rutter—where he helped grow the company from seed and led an eight-person team through a Series A—and at Instagram and Facebook working on feed and shop-tab pipelines. Comfortable across research-scale infrastructure and lean startup execution, he pairs low-latency inference engineering with practical operational skills. Unusually for his experience level, he has led hiring and team-building efforts while also shipping foundational platform code that scales to hundreds or thousands of GPUs.
