David Reis — Senior Product Designer & Engineer
Design for now.
Impact for good.

I'm a London-based Senior Product Designer with over ten years of experience bridging UX/UI design and front-end development with React. I work where product strategy meets implementation — from discovery and prototyping through to accessible, production-ready interfaces. Currently at Smartsheet, I'm shaping new experiences on the Admin Center platform; before that I led design systems and core product work at ComplyAdvantage, Ocado Technology, PetsApp, and Topdeck.
What draws me to complex B2B problems is the mix of clarity and craft: building design systems teams actually adopt, pairing with engineers on component architecture, and keeping WCAG accessibility non-negotiable. Whether it's a compliance platform, a veterinary care app, or retail supply-chain tooling, I aim for software that feels considerate to use and holds up at scale.
















Unifying legacy products through accessible design
As Design System Lead at ComplyAdvantage, I spearhead the creation of Uniform, our centralized design system, working closely with development teams across time zones to ensure accessibility and consistency are woven into every component. The work spans tokens, React components, and documentation that helps product teams ship compliant financial software faster.
