Staff product designer with ten years leading design from 0→1 to scale — across consumer, marketplace, and AI. I frame the strategy, ship the craft, and turn each win into a pattern the team keeps using — moving fuzzy problems into AI-driven, discovery-focused experiences that move real numbers.
Full case studies — Smart List AI, the Poshmark app redesign, and DecorMatters 0→6M — at xinyidesigns.com.
Led design on the 8-month app redesign across home, search, and filter — set the discovery thesis, partnered with Naver's design team on system foundations, and shipped Feb 2026. +28% Feed OI/DAU, +15% D2/D1 new-user retention, overall OI/DAU neutral by design.
Framed and shipped Poshmark's first GenAI feature, Smart List AI — authored the "draft by AI, owned by seller" pattern now used across every AI bet on the team. 68% publish rate among Smart List AI sellers (vs. 60% casual-seller goal); top-line metrics neutral by design.
Owned discovery strategy for "For You" Feed and Posh Shows (live shopping) — ranking, hierarchy, engagement loops. +60% FM, 10% YoY growth.
Set the design bar across the AI initiative — partnered deeply with US + Korea designers, PM, ML, analytics and the CPO on a mix-shift measurement framework that earned the team room to ship riskier bets.
Co-founded and led product design from 0 → 6M users across 150+ countries — through two pivots (furniture shopping → design community → social gaming), iOS + AR + responsive web, and a complete rebuild.
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 design as a founding discipline — set up the entire design practice across a 4-person team; authored the design system, brand voice, and product principles. App recognized as Apple "App of the Day"; 4.7★ rating across markets.
