• Audited four AI contract review surfaces (Word add-in, iOS app, web platform, Google Docs) and fixed login and trust issues across them • Rebuilt the iOS app from the ground up after the existing experience tested poorly with users • Designed concept flows for the AI review experience, prototyping them in Xcode and HTML so interactions and animation were resolved before development • Established a design system with color, typography, spacing and component states shared across all four surfaces
