Pinterest is the home of inspiration for millions of users. I designed across collages, widgets, notifications, and social experiences. My work ranged from 0→1 feature development to optimizing mature systems, driving user growth, engagement, and retention. Highlights include designing a scalable system for collage layouts and templates, shipping a new widget that reached 1.7M active widgets within 8 months, and leading an initiative that fundamentally shifted notifications from an isolated growth engine to an integrated product experience that deepened overall user engagement across the core app.
