Yeji Kim
Product Engineer · AI Systems · Seoul
I'm an engineer who finds genuine excitement in defining real-world problems and working through how to solve them.
From data pipelines to search infrastructure and agent execution engines, I've worked across the full stack — focused not on delivering information, but on building systems that lead to action.
Currently building AI agent systems and knowledge graph infrastructure at Factagora.
