INTERESTAI Agents

Hi, I'm GaoJunjie. I study AI, backend engineering, and reliable systems, and document the code, decisions, and failed paths along the way.

I am preparing for graduate study in AI and Computer Science. I care about reliable agents, time-series intelligence, and the engineering details that make machine learning useful beyond a demo.
