GAHYUN YOO
Product Designer
Seoul
Summary
Creative and detail oriented product designer with 8 years of experience, including 4+ years specializing in UI/UX for B2B SaaS and fintech platforms. I enjoy solving complex problems through simple, intuitive design and I’m most in my element when collaborating closely with cross-functional teams to turn ideas into real, usable products.
From building design systems in Figma to shaping full user journeys, I bring both structure and empathy to every project. With a strong background in responsive design, prototyping, and data-informed decisions, I focus on creating experiences that not only look great, but actually work better.
