Design system development

Build products faster with design systems

Building multiple digital products or planning rapid expansion? A well-structured design system eliminates inconsistencies, reduces development time, and ensures every interface reflects your brand perfectly.

We design and develop complete design systems – from Figma components to production-ready React libraries with full documentation.

Let's talk about your design system

Why you need a design system

Design systems solve real problems that slow down product teams. Here’s what changes when you have one in place.

Faster product development

Your developers spend less time building basic UI elements and more time on business logic. New products launch faster because you’re assembling from proven components instead of starting from scratch every time.

Consistent user experience

Users get the same experience across web apps, mobile apps, and different products. No more “why does this button work differently here?” questions. Every interaction follows the same patterns.

Easier maintenance and updates

When you need to update a component’s behavior or fix a bug, you do it once in the design system. All products using that component get the update automatically. No hunting through codebases to find every instance.

What we deliver in design system projects

A complete package ready for your team to use, from design files to production code.

UI design and design tokens

Complete component libraries in Figma with all variants, states, and interactions documented. Design tokens for colors, typography, spacing, and other design decisions. Everything organized for easy maintenance and updates.

Production-ready component library

Fully coded components in React (or Vue/Angular) with TypeScript support. Packaged as an npm library your developers can install in any project. Includes proper prop definitions, accessibility features, and responsive behavior.

Documentation and guides

Interactive documentation in Storybook showing every component’s variants and usage examples. Written guides covering installation, configuration, and best practices. Clear contribution guidelines for teams that want to extend the system.

When do you need a design system

Not every project needs a design system right away. Here are situations where investing in one makes clear business sense:

You’re building multiple products or applications
When you have several web apps, a mobile app, and marketing sites, a design system ensures they all feel like the same brand. Users shouldn’t have to relearn your interface with each product.

Your team is growing
As you add developers and designers, maintaining consistency becomes harder. A design system gives everyone the same building blocks and rules, regardless of who’s building what.

Development feels slow and repetitive
If developers keep rebuilding similar components for each feature, they’re wasting time. A design system lets them assemble interfaces from proven components instead of starting from scratch.

Your UI feels inconsistent
Different teams or different products use slightly different button styles, form patterns, or navigation. Users notice these inconsistencies, even if they can’t articulate why something feels “off.”

You’re planning significant growth
If you’re about to scale up product development, now is the time to build the foundation. It’s much easier to start with a design system than to retrofit one later.

You need WCAG compliance across products
Meeting accessibility standards requires consistent implementation. A design system ensures every component handles accessibility correctly, rather than leaving it to individual developers.

Our design system development process

Our process ensures the design system actually fits your team’s workflow and solves real problems, not just theoretical ones.

Every time your team starts a new feature or product, they spend time recreating buttons, forms, navigation, and other UI elements. Different developers implement them slightly differently, designers struggle to maintain consistency, and your brand experience becomes fragmented across platforms.

A design system solves this by creating a single source of truth – a library of reusable, documented components that work the same way everywhere. Your team moves faster, maintains consistency effortlessly, and scales products without multiplying technical debt.

Let's talk

Discovery and audit

We start by understanding how your team currently works. What components do you use most? Where are the pain points? What's already working well? If you have existing designs or code, we audit them to identify patterns and inconsistencies.

Component architecture

We design the system's structure: which components you need, how they relate to each other, and how developers will compose them. This includes defining your design tokens (colors, spacing, typography) and establishing naming conventions.

UI design in Figma

Your designers get a complete Figma library with all components, variants, and documentation. We work closely with your design team to ensure components match your brand and cover your actual use cases – not just generic examples.

Component development

We code each component with attention to accessibility, performance, and developer experience. Every component gets proper TypeScript definitions, handles edge cases correctly, and works responsively across devices.

Documentation and examples

We create Storybook documentation showing how to use each component, with interactive examples of all variants and states. Plus written guides for installation, theming, and contributing to the system.

Team integration and training

We help your team adopt the design system through workshops, documentation reviews, and direct support. We're available to answer questions and help solve integration challenges as they arise.

Ongoing maintenance

Design systems evolve with your products. We provide ongoing support to add new components, refine existing ones, and keep the system aligned with your team's changing needs.

Why work with Smultron on your design system

Full-cycle capability

We handle both design and development, ensuring perfect alignment between what designers envision and what developers implement. No translation gaps, no back-and-forth about “is this possible to build?”

Real product experience

We’ve built 360+ digital products over 15 years.

We understand the practical challenges of maintaining consistency across products because we’ve lived them. Our design systems reflect real-world needs, not academic ideals.

Accessibility expertise

WCAG compliance built in.

We implement proper ARIA attributes, keyboard navigation, focus management, and screen reader support. Your components work for all users, not just the majority.

Technologies we use for design systems

We adapt to your team’s tech stack rather than forcing you into ours. Whether you use React, Vue, or Angular, we’ll build your design system with the tools your developers already know.
