Hi there 👋

I'm Kangsan Lee (dgoon), a developer based in Seoul, South Korea.

I love to write programs. I love to solve problems. I love to automate.

Jack of all trades — from backend to infra, from product to AI, I enjoy diving into every corner of the stack.

I code slower than AI, but I still mass-produce bugs faster.
