Summary
👤
Senior🎓
Top SchoolJulia Wu is a founder and seasoned software leader with 11 years of experience building AI-enabled infrastructure and developer-facing systems, now scaling Spark AI to accelerate energy infrastructure permitting. She combines hands-on engineering at Apple (Siri/Knowledge Graph), Microsoft, and Brex—where she grew from SWE to engineering manager—with startup product chops demonstrated by YC W24 and multiple hackathon wins. At Brex she led fraud and risk teams that dramatically reduced operational cases, and at Apple she built search pipelines that improved relevance by 90%, showing strength in both data systems and product impact. Her entrepreneurial curiosity spans crypto/web3 prototypes, viral technical writing, and 20+ side projects that earned grants and accelerator support. Fluent in English, Portuguese, and Chinese, she blends technical leadership with cross-cultural communication and a penchant for shipping practical ML-powered systems. Based in San Francisco, she’s equally comfortable debugging production pipelines as pitching energy developers on workflows that cut bureaucratic friction.
