Design systems
Design systems that stay consistent as your product grows
A design system is the shared set of design tokens, components and usage rules that every screen in your product is built from. We build it as code, keep it in sync with your design files and test it on every change. New features then reuse existing parts instead of adding new ones.
Why does a component-driven frontend matter?
A fully component-based interface pays off in three ways:
Consistency
There's one Button, so contrast, focus rings and spacing get fixed in one place and the fix reaches every screen.
Speed
New screens are put together from parts that are already tested.
Size
Duplicate components usually bring duplicate dependencies with them. When ten features share one date picker, users download one date picker. Fewer files mean a smaller app and faster loads.
The system also gets better over time. Each improvement to a shared component improves every screen that uses it.
What we deliver
- Design tokens for color, typography, spacing, radius, elevation and motion, in the W3C Design Tokens format. They're exported to CSS custom properties, Tailwind, and iOS or Android when you need them.
- A component library with accessible primitives: keyboard navigation, focus management and correct ARIA roles.
- Every component state designed and built: default, hover, focus, disabled, loading, skeleton, empty and error.
- Storybook documentation that shows each component in every state, with usage rules.
- Visual regression tests that compare screenshots on every pull request.
- Semantic versioning and a changelog, so product teams upgrade when they're ready.
- A Figma-to-code token pipeline: when a designer changes a token, a pull request updates the code.
How do you keep a design system reliable?
A design system only stays reliable if teams trust that an upgrade won't break their screens. We set up:
- Deprecation paths with codemods that rewrite old component usage automatically.
- Usage tracking that shows which components are used where, so changes can be scoped before they're made.
- Lint rules that flag hand-rolled versions of components that already exist in the library.
- A contribution model that lets product teams propose new components without forking the library.
Pixel-perfect where it matters
Brand-critical screens such as landing pages, checkout and onboarding get implemented to the pixel against the approved design. Everywhere else, components follow the token scale, so layouts adapt to content and screen size instead of breaking at in-between widths. Skeleton and loading states are part of the design from the start, not added after users complain about blank screens.
Themes without rewrites
Components read from tokens, not hard-coded values. That means you can add dark mode, a high-contrast theme, a sub-brand or a seasonal holiday theme by switching token sets, with no component changes. Combined with scheduled feature flags, a seasonal theme can go live and come down on a set date.
FAQ
Frequently asked questions
01We only have one product. Do we still need a design system?
If more than one person builds UI, yes. Even a small token set and a dozen core components prevent drift and make the next redesign much cheaper.
02Can you build on MUI, shadcn/ui, Radix or Vuetify instead of starting from zero?
Yes. We often wrap an existing library with your tokens and your API, so you get its accessibility work without being locked into its look.
03How do AI assistants fit in?
When an assistant generates UI, we restrict it to components from your library. That way, AI-generated screens look like your product and pass the same accessibility checks.
