About

AI Product Engineer focused on agent systems, RAG, multimodal QA, and evaluation. At Supercent (Dec 2025–Sep 2026), I designed and shipped internal RAG and agentic products. Earlier, I built game AI, level-generation systems, and production tools at NCSOFT and Com2uS. I’m a Ph.D. candidate in Game Engineering at Hongik University, exploring multimodal QA, agent workflows, and AI-native interactive experiences. Portfolio: akillness.github.io/portfolio/
