‘ Taste is the real differentiator in the AI era. ’

I'm Serena Sun — shipping enterprise SaaS AI products at Walmart, and exploring what curiosity looks like through 3D, motion, and AI-native experiments on my own.

vibe lab

Driven by curiosity — exploring the edges of vibe designing, vibe coding, 3D modeling, and 3D motion. Things that didn't exist, so I built them.

What I Do

  • AI-Native Prototyping

    I design and build with AI tools — from Claude Code to v0 — turning ideas into working interfaces myself, without waiting on a full eng cycle.

  • Designing for Intelligence

    I work on the hard, unglamorous problems AI products create: uncertainty, trust, explainability, and interfaces for outputs that aren't always right.

  • Taste as a System

    I build and maintain design systems, but the goal isn't just consistency — it's a coherent point of view that holds up as products scale.

  • 0 to 1, at Enterprise Scale

    I've shipped AI-powered products from scratch inside a Fortune 1 company — navigating ambiguity, cross-functional alignment, and real production constraints.

Experience

  • Walmart

    2024 - 2026

    Senior AI Product Designer

    • Led 0→1 design of Customer Data Hub — a conversational AI platform serving 200+ users across 10+ domains, querying 30M+ subscriber datasets through natural language. Shifted the product from traditional SaaS dashboards to AI-powered proactive intelligence.
    • Designed the full AI interaction loop: natural language query → visualization → drill-down → sharing. Invented copilot-style suggestions, generative data interfaces, and confidence-calibrated outputs.
    • Solved the AI trust trilemma — transparency vs. simplicity, truth vs. trust, making failures educational. Achieved 85% trust score; 70%+ users shared AI outputs externally.
    • Cut hallucination impact through schema validation, conversational error recovery, and confidence indicators. Rate: 23% → 11%. Context-aware suggestions cut abandonment 45% → 8%.
    • Built the AI Experience Component Library with Claude Code + Figma MCP — standardizing patterns across 3 shipped products (Omni AI, ObservR, AnalyzR).
    • Pioneered vibecoding at Walmart — prototyped in Cursor AI, shipped front-end to production. Used Wizard-of-Oz testing before ML investment.
    • Operated in a 4-in-the-box model. Mentored designers, ran AI design workshops, shaped product direction across the org.
