Ziyuan L is a seasoned software leader and two-time founder with 11 years of experience building distributed systems, cryptography-driven privacy features, and consumer-facing platforms from San Francisco. As Co-Founder and CTO of Roame.travel he’s combining deep systems and encryption experience to build a Google Flights–style search for award travel, translating complex points and miles logic into scalable product. Previously he engineered privacy and encryption at scale at Airbnb and led early distributed-systems and applied-cryptography efforts, giving him rare fluency across security, backend scale, and product integration. An active angel investor in YC startups like Motion and FidoCure, he pairs builder’s instincts with investor-level pattern recognition. He brings hands-on execution—from SLAM and computer vision research to shipping React front-ends—and a bias for shipping practical, secure systems that solve messy real-world problems.
