David Lee is a UI designer who specializes in clear, system-driven interfaces. He builds component libraries, grid systems, and interaction patterns that scale across products.
His process blends fast prototyping with accessibility checks and design tokens, so engineering teams can ship consistent experiences quickly.
David focuses on evidence-based design: he tests microcopy, measures conversion lifts, and refines motion to keep interfaces calm and focused.
Achievements
- Led the rollout of a token-based design system adopted by 5 product squads.
- Increased checkout conversion by 8% through hierarchy and microcopy refinements.
- Built a reusable motion library that cut prototype time by 40%.
