Tianshu Fu

Hi Everyone!

Hi — I’m Tianshu (Tony) Fu, an AI-driven Data Engineer at Meta.
I design and deploy production-scale LLM tools, including:

Product Social Listening – a ChatGPT-style system that transforms millions of user comments into real-time product insights for Meta Quest and Ray-Ban. [Blog]
LLM Taxonomy Assistant – automatically labels datasets and identifies coverage gaps, accelerating ML prompt experiments by weeks.

Previously, I was the founding engineer at Knowtex, where I built the first version of a RAG-powered voice AI platform that converts doctor-patient conversations into structured SOAP notes, helping reduce clinician burnout. [App]
