About Hayoung

Design Medic : I Diagnose, Decode and Design


I am UI/UX designer who turns unclear briefs and chaotic feedback into structured, scalable design systems.

🩺 Diagnose : I identify the core of the problem, even when it's hidden under vague or conflicting requests.
📝 Decode : I translate abstract ideas and business needs into actionable UX strategies.
👩🏻‍💻 Design : I craft high-fidelity interfaces and prototypes that don’t just look good, but actually solve problems.

With over 10 years of experience across web comics, SaaS, travel, and global media, I’ve often been brought in when projects were stuck or undefined.
From localization mess to design system gaps, I bring clarity, direction, and consistency that always put users at the center.
