Senior Product Designer

Designing products people actually want to use.

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.

Notion AI Onboarding Redesign
Challenge
Notion AI had 68% drop-off in the first session — users did not understand what AI could do for them.
Approach
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.

Figma Component Library v2
Challenge
Figma's internal design system had 340 components with no clear naming convention, causing inconsistency across product teams.
Approach
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.
