CloudNatix
This startup specializes in cloud management and cost optimization. They needed a portal to visualize their customers' cloud usage and costs. I was responsible for the front-end development of this dashboard.
The portal was build in React and TypeScript. It used the IBM Carbon Design System as a base. For all charts and graphs I used the Victory library.
Testing was initially done with Jest but Cypress Component Testing was later introduced for a better developer experience. Storybook was used for component development and documentation.

Created a shared Design System for T‑mobile.nl and Tele2.nl. After they merged in 2019, a redesign was made for to align both corporate websites.
The Design System was created to share components between the brands and minimize implementation differences while maintaining the brands signature styling.
