CZ Vergoedingen

Reimbursement platform for CZ, one of the largest health insurers in the Netherlands, where millions of policyholders check which treatments their plan covers and how much is reimbursed.

Context

CZ is one of the largest health insurers in the Netherlands, serving millions of customers. The vergoedingen (reimbursement) platform is where policyholders check what their plan covers: which treatments are reimbursed and for how much. Because a health insurer serves everyone, accessibility was a hard requirement — every screen had to meet a11y criteria from the start.

What I did

I built the platform interface as a single-page application in React, TypeScript and SCSS, creating the component library alongside the product — every screen fully typed, documented in Storybook and unit tested with Jest. I also helped develop the design system with guidelines for layout, typography and color that future CZ applications build on.

Technical work

Fully typed React SPA with SCSS, built alongside a Storybook-documented component library. Accessibility checked per component rather than as an afterthought, with Jest unit tests keeping a critical customer-facing service reliable.
