Summary
🤩
Rockstar🎓
Top SchoolSabrina Au is a cyber security engineer based in the San Francisco Bay Area with seven years of experience bridging research and production systems. She holds a MS in Computer Science and Engineering from UC Santa Cruz and has roots in storage systems research, where she contributed as an undergraduate researcher and graduate student. At Sandia National Laboratories she applies that systems background to security engineering, pairing hands-on coding with threat-aware architecture. As an active back-end contributor to projects like Apache Pinot, she has improved scalar functions and performance-sensitive utilities—work that demonstrates attention to correctness via unit tests and real-world datastore behaviors. A first-generation graduate, she combines academic rigor in ML and storage with practical security engineering for high-assurance environments.
