● About
I'm a UX Engineer bridging design systems and frontend. Seven years shipping production UI on small teams where the lines blur between design, product, and engineering — the kind of team I work best on.
Most recently Founding UX Engineer at Mermaid (employee #4), where I took product design, frontend, and the design system from zero to production over three years. Before that, contract work at Microsoft FAST on docs and integration tooling.
AI handles the mechanical parts so I can stay focused on scope, decisions, and how things should feel.
Open source when I can — 100+ contributions across Mermaid.js, Microsoft FAST, and the San Diego Tech Hub. Mostly docs, components, and developer experience.

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.
