Steph Huynh● Intro
Open to work
UX Engineer where design systems meet frontend engineering.
I build the systems and the UI on top of them. I was founding UX Engineer at Mermaid (employee #4, through Mar 2026). Before that, Microsoft FAST. Seven years shipping production UI on small teams.
● About
I work across design systems and frontend on small teams where design, product, and engineering overlap. That is the environment where I do my best work.
I was founding UX Engineer at Mermaid (employee #4) from 2023 to March 2026: product design, frontend, and the design system from zero to production. Before that, contract work at Microsoft FAST on documentation and integration guides.
I use AI for the mechanical work so I can stay on scope, judgment, and how things should feel.
When I can, I contribute in open source: 100+ across Mermaid.js, Microsoft FAST, and San Diego Tech Hub, mostly docs, components, and developer experience.

● From a colleague
As a founding member, Steph didn't just help build the product, she shaped the foundation of the team and the culture around it. She brings strong design and product instincts, and a rare ability to turn ideas into polished, practical outcomes.
