Brian Yuan-An Liu is a Principal-level Software Engineer, Solutions Architect, Published Author, and AI/Cybersecurity Specialist with 10+ years of experience designing mission-critical distributed systems, resilient cloud infrastructure, and enterprise Generative AI architectures. With deep engineering tenures across AWS, Zscaler, and F5 Networks, he has driven the technical architecture for high-throughput cloud platforms (Aurora data streaming, Private 5G, AWS Shield, and ZIA LLM security) and engineered production-grade RAG agent workflows for real-time threat intelligence. His expertise spans large-scale cloud networking, Zero Trust architecture (CTEM), and modern LLM orchestration, backed by multiple issued and pending US patents in cloud resilience, edge acceleration, and AI security, an ACM SIGSIM-PADS Best Paper Award, and his book "The Sweet Potato Ball Protocol: An Autopsy of Modern Meritocracy". An active open-source contributor and proven technical leader, Brian pairs deep hands-on architectural rigor with strategic engineering management, making him an exceptional fit for Principal Engineer, Chief Architect, or executive technical leadership roles (Director, VP of Engineering, or Technical Co-founder).

Brian Liu Profile Picture

Brian Liu, Senior Staff Software Engineer at Zscaler and published author. Former software engineer at AWS and F5. Previously a researcher at the IIT-Security Lab with a focus on security, generative AI, distributed systems, and networking.

Outside of work, I'm a passionate guitar and bass player, heavily into metal/rock. I also enjoy the peace of fishing and camping, tackling home improvement projects, and, of course, anything involving trucks. Most importantly, I love spending time with my family.
