Hi, I'm Kim Subin, a Computer Science student at Keimyung University.

I am an aspiring Backend / Full-Stack Developer interested in building practical web services with AI-integrated features.
I have experience developing projects using Spring Boot, React, Next.js, Flask, PostgreSQL, and AWS, and I enjoy turning ideas into real, usable services.

I am especially interested in real-time collaboration systems, workspace-based service architecture, database design, API development, and AI-powered web applications.
