Making products people love.
Building AI they trust.

Hi, I'm Winnie, a Product Designer & Builder with 8+ years at Amazon, AWS, and LivePerson. I design and build AI-powered experiences, shipped products, and design systems that amplify people rather than replace them.

Mind Flux

Stoic-philosophy-based mental health app. Swipe to triage worries, AI reframes. 30+ beta users.

AI should amplify,
not announce itself.

The best AI experiences are ones users can't quite describe, because the intelligence felt so natural they didn't notice it working. I design for that invisible moment.

My background in Visual Art and Mathematics gives me an unusual lens: I see systems as compositions and compositions as systems. That dual perspective shapes every product decision.

Principles

Ambient over assistive

AI that works without demanding attention earns more trust than AI that constantly announces what it's doing.

Trust lives in the details

Error messages, loading states, edge cases, the unsexy work is where user trust is built or broken.

Accessibility is good design

100% of accessibility users preferred Libra over traditional conference rooms. Inclusion produces better products for everyone.

Build to understand

I prototype in React using Claude Code and Cursor. Understanding the material makes every design decision sharper.

8+ years at Amazon, AWS, and LivePerson designing AI-first enterprise products. I also ship my own AI side products, Mind Flux, ReferLink, and Tiny Closet.

My goal is simple: to add value. I focus on solving user problems while aligning with business objectives, creating experiences that work for everyone.
