About.
I'm a frontend developer based in Seoul, Korea. I have a dream of creating beautiful & clean services that enrich the world. When I'm not coding, I listen to jazz music, appreciate artworks and read books. I thought I could write sometimes, and made this blog.
React
My favorite frontend library
TypeScript
Saved many web devs 🙏
Next.js
This blog is built with this!
React-Native
I hope it is more maintained
TailwindCSS
Maybe this is the ONE
Emotion
Thought this was the best
Portfolio.
Rather than just building what I could, I challenged myself to create what was truly needed.

A mobile app that helps people who want to form a band find other musicians and play together. I was responsible for planning, development, and deployment in collaboration with a designer.
