Hi, I’m Sae-Hee (David)

Product Designer
(UI-focused)

I design interface systems that simplify complex products, combining front-end thinking and AI-assisted workflows to move faster and build smarter.

Interface Systems

Systems Thinking + Front-End Background

AI-Assisted Workflows

At R-LABS, I designed and developed an AI-powered venture platform that reduced research time from 3 days to 10 minutes.

Design Thinking

Designing Clarity in Complex Products

I focus on simplifying complex systems, structuring workflows, and designing products that align user needs with real business outcomes.

Complex Workflows

Structuring multi-step processes into clear, usable flows that support better decisions.
