01Overview
Start with a defined core for your design system
We define the foundations, components and rules for the UI your teams need to share. The first scope can be a core library, an existing-system assessment or a migration; we agree design and code outputs with its owners.
- Clear responsibilities for design and codeFigma specifies the intended tokens and component behavior. The coded library implements the selected parts; we agree naming and review conventions between them.
- The framework selected for your productWe assess compatibility with your existing framework and component libraries before defining the build or migration target.
- Governance with a named ownerYour team names the owner who approves component changes and release decisions. We agree contribution and maintenance responsibilities before handover.
- An inventory before commissioning changesWe compare the selected design files, components and screens. UX consulting can assess the live experience; design defines new interface requirements.

Why unicrew for design systems
Our work covers reusable code, adoption of supplied components and new UI kits. The client reviews describe the design and engineering responsibilities behind those choices.
- Bitergo: one component set, a set of applicationsFor Bitergo, we used Storybook to build reusable components for more than 15 warehouse applications. The client supplied the style guide and UX concept. In May 2022, Managing Director Andreas Trautmann described the split: we first implemented Angular components to his designer's requirements, followed by work on user frontends and REST backend integration.15+applications at Bitergo reusing the same modules, which is why the components were built once
- CaT Concepts: the components existed, the mapping was the jobRichard Klees, Managing Director of CaT Concepts and Training, in July 2026: "The new UI components already existed, key challenge was to map the existing implementations to the new ones while not losing functionality." He called our engineer "an extremely good fit to the problem that we have described," and said the team "did exactly as we agreed upon."5.0Clutch rating from CaT Concepts for the component migration, on quality, schedule and cost
- Pet4Me: a UI kit from the founder's brand directionFor Pet4Me, we mapped three core personas and their journeys. The founder created the logo and chose the color palette. We built a UI kit of typography, color tokens, components and interaction states, enabling consistent feature expansion.3core personas the one UI kit had to serve: Pet Lovers, Adoption Centers, Pet-related Businesses

Choose a focused library or assessment
A style guide or Figma component file can support a focused design scope. A UX audit assesses a live journey; design produces the screens, and a design sprint tests a concept. We define the coded library or migration when that is the work you need.
Talk it throughAgree naming and library scope
Review the components and naming conventions you already have. We agree which design or code outputs are needed and whether extending an existing library meets the scope.
Talk it throughInventory the components first
We assess selected design files, components and screens to identify coverage and differences between design and implementation. That inventory informs the core set and adoption work.
Book a discovery callPlan adoption of a core set
Agree which screens the library should serve first and who accepts the design and code. We define the component work and phased migration around those decisions.
Book a discovery callAssign governance and build responsibility
Name the component owner and agree the contribution, review and release rules. The assessment then defines the selected library work, migration and ongoing maintenance responsibilities.
Start with the auditA design system pays off on the components your teams have not built yet. We build the tokens, the components and the rules for extending them. Another team can then ship something new that looks and behaves like the rest of your product.
Andrii BurdaSenior Engineering Manager, unicrew04Capabilities
The pieces of a design system
The design system scope defines the foundations, implemented components and rules your teams need. Each capability below has its own agreed output.
- Foundations
Design token architecture
Color, type, spacing, motionDesign tokens name reusable values such as color, type, spacing and motion. We agree how Figma tokens map to coded values and how theme definitions are maintained.
- Component library development
Component libraries in your framework
React, Vue, or AngularWe implement selected components in the agreed framework, with their props, states and usage rules. Figma specifications and coded behavior are reviewed together against the acceptance criteria.
- Storybook component documentation
Storybook documentation
Next to the running codeStorybook documents the selected coded components, props and states. It was used to build components for reuse across a set of warehouse applications; documentation and test coverage are defined for your own scope.
- Design system governance
Governance and contribution rules
Owner, process, versioningContribution rules define how components and changes are proposed, reviewed and released. We agree the owner, versioning and deprecation process with the teams using the library.
- Accessible component development
Accessibility inside the components
Contrast, focus, keyboard, labelsWe agree accessibility criteria for the selected components and their uses, including contrast, focus, keyboard paths and labels. Testing and documentation record the chosen states and screen context.
- Design system migration
Migrating a library across frameworks
Across frameworks or systemsWe agree the source and target component sets or frameworks, then map the selected existing behavior. On one training-software platform, the client supplied the new components; retaining functionality was the mapping requirement.

An audit first
Start hereAn assessment of selected tokens, components and differences between design and implementation. You receive the inventory, findings and recommendations for the next library or adoption scope.
- Best when
- You want a shared inventory and an agreed view of current component coverage
- You pay
- Outcome based, quoted per project
- Typical start
- Two to four weeks
A scoped build, phased
Phased buildBuild a selected core, then adopt it on the agreed screens and review the integration before extending the scope. Design, code and documentation outputs are defined for each phase.
- Best when
- You know the surfaces the system must serve and want the estimate before you commit
- You pay
- Billed hourly, quoted per project
- Typical start
- Two to four weeks
Designers and engineers with named responsibilities, working within your practices on agreed adoption and extension work. The scope records the maintenance period, approval owner and outputs.
- Best when
- The system has to keep growing with the product and you want one team accountable
- You pay
- Billed monthly, per team member
- Typical start
- Two to four weeks
Review the system you already have
We assess selected token coverage, duplicate components and differences between the design and code. You receive recommendations to fix, extend or migrate the relevant parts. The assessment and implementation are separate decisions; underlying framework work can be scoped through legacy modernization.
07Industries
Industries we build design systems for
Component behavior follows the workflow it supports. Our software delivery experience informs the domain questions, selected states and adoption requirements of a shared library.
Logistics and transportation
Order, fleet and freight tooling, including a self-service quoting platform for a national US moving business where customers select inventory room by room without sales involvement. We assess repeated controls and interaction patterns across the selected workflow steps.
Hospitality and leisure
Booking and venue platforms, including a platform for the entertainment industry that a venue owner reconfigures for a nightclub, festival or leisure center. The library scope identifies which configurations and interface patterns it should support.
Warehouse management
A set of Angular warehouse applications built on reusable Storybook components, following the design direction the client supplied. The work supported component reuse across applications.
Financial services
Four corporate sites for a financial-services group, developed from its internal UX concepts as websites and web components. In November 2025, the client reported that all four sites had passed internal review and were online.
E-commerce
B2B and B2C storefronts with ERP integrations, including a manufacturer selling across seven EU countries whose shops were rebuilt on Shopify and connected to its ERP.
EdTech and learning
On one training-software platform, the client had already chosen the replacement components. The work mapped existing implementations onto that set, with retaining functionality as the requirement.
Bring the UI library and screens your teams need to share
Bring the existing Figma files, component library and selected product screens. We agree the intended reuse, design and code outputs, and the people who will own adoption and future changes.

09Client voices
Our clients say
The goal was to replace legacy UI elements with new UI components. The new UI components already existed, key challenge was to map the existing implementations to the new ones while not losing functionality. They were super responsive and did exactly as we agreed upon. The colleague they send to us was an extremely good fit to the problem that we have described.
After launching the site we saw a rapid increase of test accounts ordered by potential customers. Now the site provides a steady source of sales leads.
The project led to the release of our production apps and a prototype showcasing new features. They were reliable, responsive, and consistently addressed our needs very well. We were impressed by their strong technical and interpersonal skills and how smoothly they adapted to our team, processes, and product.
They built the product from start to finish. I appreciated how they thought through the process as well as the input from the business side. It’s not a situation where I tell them to code and they code it. They always give advice on what may come in the future. I’m very satisfied with their project management.
I guess the best metric is to say the work that I’ve done with them has always led to repeat business. Commitment, dedication, and talent are their greatest strengths. They really care, and I always get the impression our work together is more than just a job for them. Artelogic has the depth of talent to deliver extremely good service for any client request.

11Questions
About design system services
Agree design and code outputs, compatibility and maintenance responsibility before commissioning the system.
A design system combines reusable UI foundations, components and documented rules for using and extending them.
- Design tokens name values such as color, type and spacing.
- A component library supplies the reusable design parts and any coded implementations included in scope.
- Documentation and governance define usage, contributions, versions and responsibility for changes.
A style guide can cover visual rules; a component file can provide a design library. The agreement identifies which foundations live in Figma and which components are implemented in code.
A design system is worth assessing when shared interface work needs reusable foundations and agreed responsibility for changes. The decision follows the components and adoption work required, rather than a fixed team or product count.
We inventory the selected UI and compare extending, adopting or migrating a library. A style guide, Figma component file or existing UI library can meet a narrower scope. We recommend the design and code coverage around your actual reuse and maintenance needs.
We quote design system work against the selected design, code and adoption scope. There is no minimum engagement period.
Cost depends on:
- Components, states and frameworks included.
- Existing design foundations and the migration work required.
- Accessibility criteria, testing and documentation.
- Governance, adoption and maintenance responsibilities.
Fixed price is outcome based and quoted per project. Time and materials is billed hourly and quoted per project; team extension is billed monthly per team member. Assessment and implementation can be scoped and commissioned separately.
Build timing follows the selected components, framework work, testing and screen adoption. We estimate the schedule for the agreed scope, including design reviews and acceptance decisions.
A phased scope can deliver a core set first, then adopt it on selected screens before extending the library. Most engagements start within two to four weeks; that is a typical start window, separate from the time needed to complete the system work.
Yes. We can deliver coded components as well as Figma foundations and specifications. The scope identifies the design library, implemented components, framework and documentation you receive.
Our warehouse-application work used Storybook to build reusable components from the client's supplied style guide and UX concepts, with Angular implementation. For your system, we agree the design-to-code conventions and acceptance checks; synchronization is reviewed rather than assumed to be automatic.
Yes. We assess the selected library and codebase before agreeing what to extend, adopt or migrate. Existing components, framework versions and release conventions are inputs to that decision.
On a training-software platform, the client already had the new components. The task was mapping existing implementations onto them while retaining existing functionality. Your scope likewise records the target components, selected screens and compatibility checks, rather than presuming a complete rebuild.
We agree governance and maintenance responsibilities for the library, including an owner, contribution approvals, versioning and documentation updates.
Reviews consider proposed changes, design and code differences, and components that need deprecation. Your team can own the upkeep or commission continued work from us for the agreed period. The handover records those responsibilities and how changes are reviewed and released.
Compare the selected design and code coverage, documentation and responsibility for adoption and maintenance. Before you commission us, we define:
- The Figma foundations and coded components, with agreed states and acceptance checks.
- Documentation, migration and release responsibilities.
- The owner, contribution process and maintenance scope.
Our implementation work includes reusable Storybook components built from supplied design direction and mapping legacy implementations onto client-provided components. We distinguish those tasks from new UI-kit creation and define the corresponding outputs in your proposal.
