Notion AI Onboarding Redesign

Context
Notion AI had 68% drop-off in the first session — users did not understand what AI could do for them.
Work
Redesigned the onboarding flow around specific use cases rather than features, using contextual prompts and progressive disclosure.
Outcome
Increased 7-day retention by 34% and reduced time-to-first-AI-action from 4.2 minutes to 47 seconds.

PROJECT / 02

Figma Component Library v2

Context
Figma's internal design system had 340 components with no clear naming convention, causing inconsistency across product teams.
Work
Audited and consolidated the component library from 340 to 180 components, introduced atomic design principles and strict naming conventions.
Outcome
Reduced design-to-development handoff time by 40%. Adopted by 80+ designers across 12 product teams.

A little context

Senior Product Designer with 6 years creating consumer and enterprise products. I believe great design is invisible — it removes friction, not adds decoration. Previously led design at Notion and Figma. Currently consulting for Series A–C startups.
