A developerchanging everyday life,
Born in 2008 · High school student and developer · Jeju, South Korea
I look for the reason behind even small inconveniences,
then build better ways to solve them.
What I enjoy most is sharing the results with others.
About
When I find friction, I solve it with technology
Running a Minecraft server in elementary school first showed me that I could change the world with my own hands. Since then, solving everyday inconveniences with code has become a natural part of my life.
I go beyond writing code and build the full service journey myself—from planning and component design to development and deployment. Before making anything, I ask one question first: 'Does this service truly need to exist?'
What I work with
Next.js, React Native, TypeScript, Node.js, Nest.js, Flutter, MariaDB, PostgreSQL
Lately, I have been immersed in Vibe Coding: working with AI to shape products intuitively and turn ideas in my head into reality right away.
Projects
Most of my services began with a simple thought: 'I wish this existed.' Building those ideas has changed my everyday life, one step at a time.

Timeline
From my first line of code in 2019 to today.
Running a Minecraft server — my first steps in coding
I taught myself PHP because I wanted to build a Minecraft server. By reading, modifying, and rewriting other developers' code, I learned to create plugins within a year and naturally moved into web development.
Built and operated CrossFarm · led a team of nine
What began as a solo project grew past 30,000 cumulative players. I assembled and led a nine-person team, learning the weight of large-scale operations, organizational management, and the value of collaboration.
Transition to modern web development
I moved beyond basic PHP websites and dove into the modern frontend ecosystem, including React. Learning component-based architecture and state management marked my transition to a more structured, scalable approach.
Transition to JavaScript / TypeScript full-stack development
I fully adopted the Next.js and NestJS stack. Building services used by real schools and students, including ACE Timetable and MogoMogo, taught me production development while I owned every decision from technology selection through deployment.
Started building LLM-powered services
I built a series of LLM- and RAG-powered products, including Jejueo Translator, which preserves UNESCO-listed endangered Jejueo, Academing, and Purn Note. I explored not only using APIs, but protecting a unique culture and creating practical impact through technology.
App-store launch & still building
Wordie is launching on the App Store and Play Store (planned for March 14), while Jejueo Translator is moving forward with relevant organizations. I continue solving the everyday problems I encounter as a student and changing ordinary life with my own hands.
