I turn service breakdowns
into working products and systems.
I'm EJ Jung, also known as Euijin Jung: a product designer, co-founder, and builder working across strategy, research, design, and code. I have co-founded healthcare and AI-enabled service products, led federal UX across 16 agencies, and built design infrastructure for institutional teams.
