Design System
Posti Design System
I led the development of the design system for Posti, Finland's national postal and logistics company: one set of accessible, reusable components for many product teams.
The client
Posti runs a wide range of consumer and business services, built by several teams at once. Without shared building blocks, every team ends up rebuilding the same buttons, forms and layouts, and the experience drifts apart.
What I built
- Led development of the component library in React and TypeScript, styled with Styled Components.
- Made accessibility a baseline requirement for every component, not an afterthought.
- Built the components to be reused across multiple teams and products.
