Steph HuynhAs 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.
● Intro
UX Engineer Where product design, design systems, and frontend engineering meet.
I think in systems, starting with frameworks like Superbloom, the design system behind this site, then building the UI on top of them.
● About
I work across product design, design systems, and frontend engineering, on small teams where the three overlap. That is the environment where I do my best work.
I'm currently a UX Engineer at Monoline, the modern quoting and binding platform for standalone personal umbrella insurance: migrating the design system from v1 to v2, plus the internal tools underwriting and operations run on. Read the case study →
Before that, I was the founding UX Engineer at Mermaid (employee #4) from 2023 to March 2026: product design, frontend, and the design system from zero to production. Prior to Mermaid, I contracted with Microsoft FAST on documentation and integration guides.
I use AI for the mechanical work so I can focus on what to build, why it matters, and how it should feel. I'm also extending that mindset beyond my own work, to how a team works, not just what it ships.
When I can, I contribute to open source: 100+ across Mermaid.js, Microsoft FAST, and San Diego Tech Hub, mostly docs, components, and developer experience.

Currently building at Monoline.
I own the product UX across Monoline's suite: research, wireframes, prototypes, and production interfaces, plus migrating the design system from v1 to v2.
That includes the internal tools underwriting, operations, and support rely on daily, partnering with engineering on interaction patterns and architecture, and building production code myself in the same codebase.

The design system behind this site.
Superbloom is the component library I built for this portfolio: tokens, patterns, Storybook, and docs in the same repo. Every page here is composed from it.
Built in the open and shipping with the site today.

● From the Mermaid team
Read Mermaid case studySteph has a knack for creating great user experiences! Not only has she designed (and re-designed!) entire sites and user-flows, but she built up a culture of strong UX design with reusable components and internal processes.
Steph is passionate about her work, focuses on quality and is good at communicating and collaborating with team members. In addition to her skills as a UX Engineer, I really liked her ambition to create a good team culture.
