Top SchoolMatt Simon is a founder and senior frontend specialist with over 15 years’ experience delivering accessible, performant user interfaces for government and major brands, including leading the front end for the UK Census 2021. He builds design systems and pattern libraries from the ground up to provide consistent, modular front ends consumed across dozens of services, with a strong focus on accessibility, performance and user experience. Currently he is shaping a custom design system for the UK Department for Business and Trade while also launching Chatworks, a WhatsApp-native invoicing product for tradespeople. Matt combines hands-on coding (modern JS, React, design tokens, CSS custom properties) with interaction design and stakeholder-facing communication, running workshops and accessibility testing. He’s comfortable taking projects from research and prototypes through production at scale, and often champions pragmatic, tech-agnostic solutions that make reuse and theming straightforward. Based in Cardiff, he pairs agency-speed delivery with public-sector rigour, delivering systems that survive heavy traffic and diverse user needs.
