Jeonghwan Kim

Software Engineer

I architect the system, build the product, and ship the code.

About

I care about people. I started in neuroscience research, designing a game that helps reduce depressive symptoms through brainwave regulation. That experience taught me that small UX decisions create real human impact.

Now I build software end-to-end. I do the system design, write the code, and ship it myself — full-stack web, native iOS/watchOS, and real-time systems. Every project in my portfolio was built by me, not just managed.

I care about the product I'm building, so I think about the user and the business while I'm engineering. That overlap is where I do my best work.
