Hi, I’m Injae 👋

I’m an AI Engineer working on NLP, LLMs, and RAG, and a master’s student in the Department of Big Data at Sungkyunkwan University (SKKU).

I design and run LLM-powered systems in production — RAG-based search, model routing and serving with vLLM, and domain-specific sLLM fine-tuning. I like taking an idea all the way from research to a reliable service.
