4 years building production web applications · Enschede, Netherlands
I build product interfaces and reusable UI systems with TypeScript, React/Next.js, and Angular — from Figma and component architecture to testing and production.
I have been building production web applications since October 2022: three years of Angular in healthcare, and React and Next.js today. Most of my work starts at a Figma file and ends in production — component architecture, design tokens and a shared UI library, state and API integration, responsive and cross-browser layouts, accessibility, Storybook, and unit and end-to-end tests with Vitest, Cypress, and Playwright. I like taking a feature end to end and shipping it genuinely finished: consistent with the design, true to the requirements, tested, and fast.
At Neolook I built the frontend of healthcare software for neonatal and pediatric intensive care, deployed in hospitals including Máxima MC, UMC Utrecht, and UMC Groningen: real-time camera monitoring over Server-Sent Events, multi-person video calls with WebRTC, license-based feature and route protection, Dutch–English localization, and dark mode. Today, at Junior Einstein, I work on a large educational platform for primary schools — not one application, but several connected products on different stacks: a webshop and content pages on Next.js, and the learning environment itself as a React SPA. I build product features and reusable UI components with MUI, shadcn/ui, and Tailwind CSS, keep the interface faithful to the design, and shape the Figma-to-React workflow the team uses to turn designs into components.

Generating UI from a Figma design only works if the design is structured for it. Much of the work sits on the Figma side; the AI step comes last.
