Steph Huynh, UX Engineer

UX Engineer where design systems meet frontend engineering. I build the systems and the UI on top of them.

Founding UX Engineer at Mermaid (employee #4, Jan 2023 to Mar 2026): product design, frontend, and the design system from zero to production. Before that, Microsoft FAST (contract, 2021 to 2022) on web components docs and Docusaurus infrastructure. Seven years shipping production UI on small teams where design, product, and engineering overlap.

I also build and maintain Superbloom, my own OKLCH token-driven design system: 7 primitives and 7 patterns on a foundation of semantic tokens, documented in Storybook with Argos visual regression on every pull request.

What I do: UX/UI · product design · frontend engineering · design systems · prototyping · documentation · developer experience

Stack: SvelteKit · React · Next.js · TypeScript · Tailwind · shadcn/ui · Storybook · Figma

Open source: 100+ contributions across Mermaid.js, Microsoft FAST, and San Diego Tech Hub. Docs, components, and developer experience.
