8 years of UX across North America, Europe, and Asia taught me to design for how different people see the world, shaped by real cross-cultural insight.

Design lives between logic and feeling.That’s where I do my best work
I start with understanding users, goals, and constraints before touching a screen. From there it’s structure, then interface, then testing and refinement. Because I also build, I can move from concept to a working, testable product in one continuous flow, so ideas get validated early instead of living in a static mockup.
My background spans a variety of industries (e-commerce, entertainment, education and more) across North America, Europe, and Asia. I design with cross-cultural users in mind, tailoring my approach to what each market or business actually needs. Having worked on both long- and short-term projects across B2B and B2C, I’m adaptable across fields and always eager to dive deeper into something new!
I’m used to working across cross-functional teams like product management, engineering, research, data analytics, and marketing. I’m comfortable translating between them: turning research and data into design decisions, and design decisions into something engineering can build. Whether you need me embedded in a team or working independently and syncing at milestones, I adapt to how you already work.
It depends on the work. I run on a flexible cycle rather than a fixed one. I’ve delivered fast, focused sprints (a landing page or a feature in a week or two), and I’ve committed to long-term builds that run for months. Tell me your deadline and scope, and I’ll shape a plan that fits.
Absolutely. If you already have a brand system, I design within it, respecting your type, color, and voice so everything stays consistent. And if there are gaps, I’ll flag them and can extend the system where it needs to grow, without breaking what’s already working.
The fastest way to reach me is by email at doyeon.sung.design@gmail.com. I usually reply within one business day. If you’d rather talk it through, just request a call in your first email and we’ll figure out whether it’s a fit.
