Design Systems Development

ONE SYSTEM,EVERYSCREEN

We build design systems for product teams that have outgrown ad hoc components, with a Figma library, coded React components and design tokens kept in step through shared documentation.

01Our Approach

We build a design system as a product with users, releases and owners, so the Figma library and the code stay in agreement.

02Overview

One source of truth for design and code

  • 01Figma libraries
  • 02Coded components
  • 03Design tokens

A design system is the shared set of tokens, components and rules your products are assembled from. We build both halves, a Figma library with variants and auto layout for designers and a typed React component package documented in Storybook for engineers. Tokens for color, type, spacing and elevation connect the two, so a change made once reaches every product.

It pays off when several teams or products share an interface, when the same button exists in five slightly different forms, or when you need to theme one platform for multiple brands. We begin with an audit of what already exists, keep what works, and build the system in the order your roadmap needs it instead of trying to finish everything upfront.

03What We Do

Capabilities, End to End

01
Interface audit

An inventory of the components, colors and type styles in your current products, showing duplicates and inconsistencies and giving the system a prioritized starting list.

02
Design tokens

Color, typography, spacing, radius and elevation defined as named tokens in a standard format, then transformed into CSS variables and platform values from a single source.

03
Figma component library

Components built with variants, properties and auto layout, published as a team library with usage notes so designers assemble screens instead of redrawing them.

04
Coded React components

Typed, accessible components built on tested primitives, with keyboard support and focus management, packaged for npm and documented with live examples in Storybook.

05
Theming and dark mode

A token structure with semantic layers that supports dark mode, density options and per-brand themes, so white-label products change appearance without forking components.

06
Governance and releases

Versioning, changelogs, contribution guidelines and visual regression tests in your pipeline, so the system keeps evolving safely after the first release is published.

From Kickoff to Launch

01
Audit

Foundations
03
Build components
04
Adopt
01
Audit

We inventory the components and styles across your products and code, interview designers and engineers about what slows them down, and agree on which components the first release must cover.

02
Foundations

We define the token structure, naming conventions, type scale, color roles and spacing rules, then prove them on a few real screens before any component is built on top.

03
Build components

Each component is designed in Figma and coded in React in the same cycle, with matching property names, accessibility checks, tests and a Storybook page reviewed by both disciplines.

04
Adopt

We migrate a first product area with your team, publish the package and library, set up release automation and hand over contribution guidelines so your people can extend the system themselves.

08Who It Is For

Built for Teams Like Yours

FLAGSHIP
Several teams are building the same components differently

Each squad has its own buttons, modals and form styles, designers redraw what already exists, and a brand update means touching every repository. You want one maintained library that designers and engineers both trust, with a way to change it without breaking products.

Multi-product enterprise platforms
Growing SaaS product interfaces
White-label and multi-brand theming
Rebrands across many screens
Migrations from legacy UI kits
Shared web and mobile components
09Questions

What buyers ask before they start

If yours is not here, ask us directly. The first conversation is free and useful whether or not we work together.

A component library is one part of a system. If a single team ships a single product, a well-organized library in Figma and code is often enough, and we will say so. A full system adds tokens, theming, documentation, versioning and governance, which matter once several teams or brands depend on the same parts. We size the work to how many people will use it.

Yes, and we prefer it. The audit shows which existing components are sound, which need refactoring and which should be replaced. We keep your framework and styling approach where they serve you, introduce tokens underneath the components you already have, and migrate product areas gradually. Old and new components can coexist during the transition, so teams keep shipping features while the system takes shape.

Three things. Tokens live in one source and are exported to both Figma variables and code, so values cannot drift. Component names, variants and properties match between Figma and React, which makes differences obvious in review. And every change goes through one release process with a changelog covering design and code together. We also link Storybook pages to their Figma counterparts.

Components are designed and coded to WCAG 2.2 AA criteria. That means sufficient contrast in every theme, visible focus states, full keyboard operation, correct roles and labels for assistive technology, and respect for reduced motion settings. We test with automated checks and with screen readers by hand. A system cannot make a whole product accessible alone, so the documentation also explains correct usage.

Ideally your own team, and the system is set up for that. You receive the repository, the Figma library, release automation and contribution guidelines that explain how to propose, review and publish a change. We pair with your designers and engineers during the build so they know the internals. If you want continued support, we can stay on for new components and reviews.
