Seoul, Korea

Product designer,
beyond the screen.

I’m Hyeokgyu Jang. I design for the people and systems behind an experience, not just the person using it.

Portfolio System

1 / 3

I wanted the site to show how I work, and to keep getting better.

The first version was a set of pages. As projects grew, writing, images, and style rules drifted apart, and AI edits could quietly touch the live site. So I treated the portfolio as a small product: a clear structure, one design system, and a safe way to change it.

Day1Company N-job Research

1 / 3

The brief was research. The data asked for more.

Through a Future Work Experience internship at Day1Company, I researched the side-hustle (N-job) education market for zero-base. Once the data showed what 2030 N-jobbers were looking for, I extended the work past the report and into the detail pages.
