About
I am a software engineer at LG CNS, where I build AI-powered systems and full-stack web applications. My recent work focuses on designing agentic workflows with LLMs, building multi-modal RAG pipelines, and developing enterprise-scale platforms with Next.js.
I hold dual degrees in Linguistics and Computer Science from Korea University. Outside of work, I contribute to open source, mentor engineers on AI-native development practices, and maintain a 2,000+ day streak on Duolingo across four languages.
