About
I'm Jeongsic Yoo, an engineer and designer who started in design and grew into front-end development.
It started with design
I first became interested in design while looking through the work of Karim Rashid and Stefan Sagmeister. That's how I started studying design, and I wrote down the books I read while studying and the thoughts that came with them. My design book review series was also published in Notefolio Magazine for a while.
From web design to front-end
Designing for the web, I wanted the screens I drew to actually move and respond. That wish led naturally into front-end development, and turning design into code slowly became the center of my work.

Between design and development
Early in my career I kept asking myself, “Am I a designer or a developer?” I see that ambiguity differently now. Just as dithering makes a richer picture out of a few colors, moving between design thinking and engineering has given me my own way of seeing and making.
I work hoping the things I make help us love our lives a little more, and inspire us along the way. In the AI era, I want this place to hold a wider range of experiments and stories, too.
Outside of work
I run or read. A long time ago I finished a full marathon, and these days I enjoy easy runs. I like books of all kinds, but I'm especially fond of the books of Seth Godin, known as a marketing guru.
Get in touch
Always happy to talk about the work or the writing.
