🚀 Projects
A collection of projects I’ve participated in, including IT club activities and team development work.
PloGo – Plogging Course Recommendation App
Graduation project for Hongik Univ. 2025. PloGo is a mobile app for recommending and logging plogging courses at eco-tourism sites in Korea. Built with Flutter, it supports Android, offers course recommendations, map-based activity logs, photo uploads, search by region, and Kakao login. Developed core features and UI/UX, focusing on user-friendly experience and stable cross-platform deployment.
Hongik DevTalk Seminar Website
Hongik University DevTalk Seminar Website is the official platform for seminar registration and management. As the Frontend Lead, I designed the overall design system, layout, and routing structure. I implemented the admin dashboard, administrator account management and login UI/logic, and developed the user seminar application modal. The project focused on scalable architecture and intuitive UX for both administrators and users.
Totok Totok – Reading Habit App
Started from the concern that people struggle to build reading habits, Totok Totok is a mobile app that helps users visualize their reading progress, record one-line reviews and pages read, and stay motivated. Integrated Kyobo Bookstore Open API for automatic book info, real-time saving, and intuitive UI for enhanced usability.
WOW MARKET – University Goods Commerce
Noticing the inefficiency of scattered university goods trading, WOW MARKET is a web service for easy registration and trading of student-made goods. Features include school-based product categorization, demand survey, responsive UI, and product management. Developed frontend with React and JavaScript, focusing on clean UI and targeted commerce experience.
ESCAPE-T
A 2D puzzle escape game set in the T-building (Engineering Hall) of a university. Players explore different floors, gather clues, and solve puzzles to escape. I participated in every step—planning the scenario, designing levels, implementing logic, and directing UI flow—using Unity and C#. This project won the Silver Award in our university’s project competition.
