LottieFiles.Previously, I led the design of 
ProtoPie Studio and worked on the system UI for Astell&Kern hi-fi audio players and on enterprise software.
Lately, I’ve been expanding my work into design engineering, building ideas myself with AI tools and bringing designs into the real product through code.

At Lottie Creator, I built code-based prototypes instead of explaining with documents and guides, and fixed problems found in design QA in the code myself and merged them. A design engineering case study covering Motion Tokens, the shortcut modal, and the timeline cursor.
ProtoPie
About 80% of ProtoPie users start their designs in Figma, so it mattered to keep the habits they already had and ease what they had to relearn. I used the Auto Layout launch to redesign the property panel enterprise customers kept asking to improve, and to overhaul the design system.
SK Inc. C&C
Accuinsight+ is an enterprise platform for data analysis. To find the problems, I tried the analysis work myself and observed how real users worked. That experience shaped a more intuitive redesign of the Workflow, its core feature.
SK Inc. C&C · AUD Social Cooperative
ShareTalk turns speech into live captions to help deaf people communicate. User interviews revealed the difficulties students face in class, and prototypes with real interactions uncovered problems that static screens couldn’t show.
IRIVER
The A&ultima SP1000 was Astell&Kern’s first flagship model. Moving away from a UI that had barely changed for years, I designed a new interface around the character of the brand and hardware. Depth, light, and layers convey the sense of space in sound, and the UI covers the whole product, from boot to system settings and device connections.
SK Inc. C&C
UX Labs ran design thinking workshops for people across SK. Accu Design Kit is a toolkit that lets anyone use the methods from those workshops on their own. We built it for employees, and a strong response led us to open it to the public.
IRIVER · SK Telecom
A concept project to add a display to SK Telecom’s next AI speaker. I led the visual design, exploring how an AI speaker could express emotion visually and developing the concept around the form, range, and movement of its expressions. The project ended at the concept stage.
