Projects
Wasabi Farming Management App (Bachelor Thesis)
Developed a mobile application for wasabi farmers in Shizuoka, Japan to help monitor cultivation and harvest.
Problem: Japan’s agricultural workforce is rapidly aging, with nearly 60% of farmers over the age of 65. As eyesight, reaction speed, and physical stamina decline, it becomes increasingly difficult to monitor crops closely and detect disease in time.
Solution: Developed a mobile application that allows farmers to monitor their crops and identify sick wasabi leaves earlier, helping prevent waste and reduce the risk of crop failure.
Tech Stack: Google Colab · Python · Java · LLM · Android
Peoples — Study Community App
Teamed up with six members to develop a mobile application for a startup in Seoul that connects students who want to study together.
Problem: Students often struggle to find consistent study partners or communities for job interview preparation, tech meetups, language learning, and 'mogakko' (independent group coding sessions).
Solution: Developed a mobile platform where students can organize study sessions, check in to meetings in real time, track attendance, and stay motivated through group learning.
Tech Stack: Kotlin · Java · Springboot · Compose
Korean Language Learning Platform
Developed an online learning platform where Korean language learners can ask questions and share knowledge about Korean language and culture.
Problem: Large communities such as Reddit allow discussions but are not optimized for structured learning or reviewing previously discussed topics.
Solution: Created a platform where discussions become organized learning resources. An integrated AI quiz generator helps learners reinforce knowledge based on community discussions.
Tech Stack: Next.js · Tailwind · Shadcn UI · Firebase · Claude API · Vercel · Google Analytics
Germany–Korea Cross-Border Shopping App
Developed mobile apps enabling Korean customers to browse and purchase popular products from Germany.
Problem: Major marketplaces such as Coupang or Naver Shopping charge high seller fees and often provide limited transparency for international shipping.
Solution: Built a mobile platform allowing customers to shop curated German products with simplified customs information and transparent real-time shipping tracking.
