Summary
👤
Senior🎓
Top SchoolSophia Cui is a technical co-founder and former early Uber engineer with 13 years of experience building high-throughput, algorithmic backend systems and scaling teams through hypergrowth. She helped create Uber’s mapping, routing, and Freight foundations—designing systems that handled hundreds of thousands of requests per second and earned multiple patents—then pivoted to founding Supra Technologies where she built an ML-driven trading platform that executed $221M in trades and trained over 50,000 models. Equally comfortable managing teams and shipping low-latency infrastructure, she specializes in distilling massive nightly ETL pipelines into dozens of production strategies and turning research-grade ML into disciplined, product-aligned systems. A hands-on maker at heart, Sophia prototyped an apple-picking robot during a world travels sabbatical, reflecting a practical curiosity that drives both hardware and finance projects. Based in Berkeley, she combines startup grit with deep technical rigor and an unusual appetite for turning adventurous prototypes into profitable, scaled products.
