Full case studies — Smart List AI, the Poshmark app redesign, and DecorMatters 0→6M — at xinyidesigns.com.
Led the 8-month app redesign across home, search, and filter — launched Feb 2026 with Naver's design team on system foundations. +28% Feed OI/DAU, +15% D2/D1 new-user retention, with overall OI/DAU neutral by design.
Shipped Poshmark's first GenAI feature, Smart List AI — owned end-to-end UX from framing to A/B test. 68% publish rate among Smart List AI sellers (vs. 60% casual-seller goal), top-line metrics neutral by design.
Designed the personalized "For You" Feed and drove Posh Shows (live shopping) discovery — ranking, hierarchy, engagement loops. +60% FM, 10% YoY growth.
Coach two designers; partner with PM, ML and analytics on a mix-shift measurement framework that earned the team room to ship riskier bets.
Co-founded and scaled DecorMatters from 0 → 6M users across 150+ countries; led product design across iOS, AR, and responsive web through two pivots — furniture shopping → design community → social gaming.
Drove the community pivot — publish rate ×4.2, likes ×2; then the monetization pivot to a game-economy model (gifts + Dcoins + membership) — revenue ×6, 3× the original 2× goal.
Built the design system; hired and grew a 4-person design team. App recognized as Apple "App of the Day"; 4.7★ rating.
