Brian Yuan-An Liu is a Principal-level Software Engineer, Solutions Architect, 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, along with an ACM SIGSIM-PADS Best Paper Award. 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, Senior Software Development Engineer at Zscaler. 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.
