Résumé · updated July 2026

Yuchen Zhang

Founding Product Designer · San Francisco

Founding product designer who turns ambiguous, high-stakes workflows into clear, trustworthy AI products. I've owned 0 → 1 products across fintech, autonomous systems, and AI commerce, designing how people trust and act on AI (grounded, human-in-the-loop, auditable). I prototype fast with Claude Code, Figma Make, and Lovable.

Founding Product Designer

  • Built a cross-product, cross-device design system from scratch, speeding cross-functional alignment and iteration.
  • Shipped a 0 → 1 AI customer-support system (RAG + LLM) with grounded citations, an answer/route/escalate taxonomy, and a human-in-the-loop review queue, now live with daily results logged to a Notion database to track deflection.
  • Owned the 0 → 1 design of a merchant operations app with two AI workflows and guardrails (status-aware eligibility, audit trail); shipped iOS/Android with 3x growth in 2 months and 20% fewer support tickets.
  • Rebuilt a complex B2B onboarding flow with AI-accelerated prototyping, cutting setup effort ~30% and aligning PM and engineering in days.
  • Overhauled the UX of a high-volume payment app (8,000+ terminals, 400K+ weekly transactions), cutting operational errors with role-based UI and state-driven interactions.
  • Worked at founding-team scope: partnered with the CEO on strategy and investor decks, and shaped GTM and enablement materials.
