01 — About

Yonsei University

I am an industrial engineering student at Yonsei University who builds AI-assisted tools with and for teachers in special and vocational education. Serving as a social service agent at Saesol School, a special education school, I support students with disabilities in daily school life and develop web tools with teachers, from interactive class tools for recycling and everyday-English lessons to a café job-training kiosk. I also built a mock exam grading and analytics app used by about 60 vocational high school students, train teachers to build their own classroom tools with AI, and work natively in Korean, English, and Mandarin Chinese.
