Summary
👤
Senior🎓
Top SchoolYu-cheng Liang is a Senior Staff SRE and Security Architect with 10+ years designing large-scale identity and access management systems across Google, Uber, and NVIDIA, where he now leads AI agent identity strategy. He blends deep IAM engineering—ACL recommenders, privileged access platforms, and lateral-movement mitigations—with applied AI/ML and LLMs to automate access decisions and discover risky access paths at scale. At NVIDIA he architected a platform-agnostic hybrid/federated model for non-human identities that aligns with emerging ODIS and NIST efforts, while at Uber and Google he built production AI-driven approval and recommender systems that measurably improved least-privilege adoption. His background ranges from low-level authentication and SMB protocols to cloud-native JIT PAM, giving him a rare full-stack security perspective. Based in Sunnyvale, he complements his industry work with personal ML projects—GANs, image captioning, and recommender prototypes—demonstrating continual hands-on experimentation beyond corporate initiatives.
