THE PERSON BEHIND THE PROJECTS

LESS TALK.
MORE WORKING SOFTWARE.

I’m Madan Park, a builder based in Seoul. I’m interested in what happens when a useful idea meets a working prototype.

I built and sold EUJobs. I make tools for AI conversations and experiment with voice, accessibility, and policy technology. Hackathons are where I meet collaborators, test strange ideas, and learn by making.
