Summary
👤
Senior🎓
Top SchoolMark Learst is a Senior Design Engineer with 14 years building resilient design systems, accessibility-first component libraries, and developer experience tooling that eliminate handoff friction between design and code. He’s shipped cross-brand systems at GM (Aurora) with 60% reuse and WCAG 2.2 AA compliance, trained 50+ engineers and designers, and now drives workflow-heavy UI orchestration at ZoomInfo. A prolific OSS maintainer, Mark publishes practical tools like a11y Companion and FigmaVars Hooks that have real users and integrate WCAG checks into design tooling. He blends deep front-end craft (React 19, TypeScript, Storybook) with CI validation gates, agentic workflows, and Figma automation to keep dynamic UIs typed, accessible, and on-brand. Beyond code, he’s known for building the “glue” — token pipelines, validation, and primitives — that let teams move fast without drifting.
