Hun Kim is a software engineer with five years of experience building production data systems, real-time collaboration tools, and AI-driven search and tooling. With a dual background in computer science and visual communication design and a Master’s in Design Engineering from Harvard, he bridges UX-aware product design and backend engineering. He has shipped features at scale—from performance monitoring contributions to the open-source Pinpoint APM project to a multiplayer whiteboard on NAVER using Yorkie—and led system design for API monitoring and hybrid semantic search at DALPHA. His work often sits at the intersection of data, visualization, and human-centered AI, including prototyping LLM-powered knowledge systems and automating GIS workflows for urban research. Colleagues would note his knack for turning research insights into production-ready dashboards and internal tools that accelerate product iteration.
