Code Place Platform

Code Place is Pusan National University’s official online judge platform, used by approximately 800 real users for programming practice and coursework.

As a Student Researcher at the AI Convergence Education Institute, I participated in platform maintenance, feature development, operational troubleshooting, and the development of an AI teaching assistant.
