Xi Zhang
Full-Stack Data Scientist
Irvine, CA
Where artificial intelligence meets scalable engineering.
I architect AI systems that turn raw data into intelligence — from LLM orchestration and RAG pipelines to full-stack platforms that scale. 5+ years building at the intersection of machine learning and product engineering.
At Stout, I've architected enterprise AI platforms that process thousands of governed LLM interactions daily — blending RAG pipelines, graph databases, and full-stack delivery. Outside of work, I ship the Flux product suite: AI-powered platforms for career intelligence, financial management, and metabolic tracking.
