Hello, I'm Sungmin Cho, a frontend developer.

I first got interested in web development in high school, and I now build products mainly with React and Next.js. I'm also interested in app development with React Native and Expo.

I graduated from Korea Digital Media High School, where I majored in Web Programming, and I'm now studying Statistics at the University of Seoul. I'm learning to read and interpret data, a skill I want to bring to the products I build. I keep exploring what can be built at the intersection of development and statistics.

I believe building a screen is ultimately about designing the user's experience. That's why I've been learning Figma alongside development since high school. I even designed a book in Figma.

At the same time, I don't think a good experience is complete just because it looks good. However well a screen is designed, if the first paint is slow or input feels laggy, users leave before they ever experience that design. So I pay close attention to rendering strategy, bundle size, and unnecessary re-renders, and verify improvements with metrics.

Across many projects I've handled not only development but also product planning and design. That's taught me to look at a product as a whole, not just one part of it.
