Independent builder / Seoul, Korea

I build my
own universe.

When something in my life feels missing, I make a tool for it. What started with one problem has become a constellation of products I actually use.

02 / THE SYSTEM

Different tools.
One way of thinking.

I don’t start with a category or a business plan. I start with friction—and keep refining until a tool becomes part of my life.
