01Overview

Design for a product decision you have already made

We turn your product direction into a defined screen set, starting with the flows you want to release. A first design engagement can cover one flow; we agree its research and implementation requirements before drawing it.

  • Feasibility before sign-offEngineering reviews the proposed interactions against your codebase and constraints before you approve the production screens.
  • Design and build responsibilities agreedYour scope names who designs, who builds and how engineering and ISTQB-certified QA review the work.
  • Research before pixelsWe agree the user research each flow needs. Personas describe its users; journey maps show the steps they take through the product.
  • WCAG 2.1/2.2 AA in scopeWe agree accessibility criteria for the selected screens, including color contrast, keyboard navigation and screen-reader behavior. Implementation testing follows the build scope.

02Proof

Why clients choose us

We connect interface design with its implementation, including work from concepts and components a client already owns.

  • Four accessible sites from the client's UX conceptsWe developed four corporate websites for a financial-services group from its internal team's UX concepts. The build included responsive layouts, accessibility implementation and technical QA. In November 2025, Senior UI/UX Designer Tanja Stuchels reported all four sites live and said: "The accessibility scores are top-notch, and the user engagement is higher."
    4corporate sites live, each one held to the same accessibility bar
  • CaT Concepts: modern components, existing functionalityCaT Concepts supplied the new components for its training application. One unicrew engineer carried out the modernization, mapping the existing implementations to those components to retain functionality. Managing Director Richard Klees described the fit in July 2026: "The colleague they send to us was an extremely good fit to the problem that we have described."
    One engineercarried the whole mapping, matched to a problem the client had already named precisely
  • Pet4Me: research translated into a UI kitFor Pet4Me, we mapped three core personas and their end-to-end journeys before designing the marketplace interface. The founder supplied the logo and color palette. We developed the UI kit around them, with typography, color tokens, components and interaction states that gave engineering a reusable design foundation.

Start with an audit or a design system

For a diagnosis of a live interface, start with a UX audit. For reusable components and their upkeep across products, scope a design system. We can also design a defined screen set from the concepts your team already owns.

Talk it through

Define the interface work first

We review the flows you want designed and the expertise your team already has. The conversation establishes the design deliverable and the engineering input it needs.

Talk it through

Worth scoping as a design engagement

Agree the first screen set and its research requirements before commissioning the design. We define the review responsibilities and outputs with your product and engineering leads.

Book a discovery call

Coordinate the design and build

Start by agreeing which screens need design and who will implement them. We include engineering review in the design scope and define the component outputs that support those screens.

Book a discovery call

Design and build in one engagement

We can combine interface design and implementation in the agreed engagement. Define the first flows, the research they need and the acceptance criteria for the build before work starts.

Talk about the work

We design for the person who opens your product for the first time. We map a customer journey for each persona and test prototypes with real users. That shows early how easily people grasp the product's benefits and complete the journey you intend.

04Capabilities

What do you need designed?

We design the interface for your selected product direction. The services below cover its web and mobile screens and the adjacent purchases; a UX audit diagnoses a live product before you decide what to redesign.

  • Product design and development

    End-to-end product design

    First interview to first release

    Discovery, research, interface design and software engineering through launch. Scope the complete product when you want responsibility for the working software alongside the design.

  • Web application UI/UX design

    Web app and website design

    Real breakpoints, real content

    We design portals, dashboards, internal tools and corporate sites around their users, content and agreed breakpoints. Accessibility implementation and technical QA were part of the build for four corporate sites from a client's UX concepts.

  • Mobile app UI/UX design

    Mobile app design

    iOS and Android

    We design the selected iOS and Android flows around touch interaction, interruptions and connection states. The scope sets how the mobile app and web app share interface patterns.

  • Design systems and component libraries

    UI kits document typography, color tokens, components and interaction states, as on a researched marketplace interface. A reusable design system adds the shared implementation and upkeep needed across products; we scope that work separately from a screen set.

  • Design sprint facilitation

    Design sprints use rapid prototypes to test an unsettled concept with users. Choose this scope when you want to assess a direction before commissioning production screens or software engineering.

  • Legacy UI modernization

    We map the agreed legacy screens and behavior onto modern components. On one training-software platform, the client supplied the replacement components; the requirement was to map existing implementations without losing functionality.

05Trust

What a design engagement hands over

We agree the screen states, reusable outputs and handover terms before work starts. These deliverables cover the selected flows, with design and build responsibilities recorded in the scope.

  • Every stateThe empty, loading and error screens, not only the happy pathFor the selected screen states, redlines specify behavior and identify who owns design and implementation
  • A libraryComponents, tokens and interaction states, with usage guidelinesSelected components, tokens and states document interface reuse within compatible designs and code
  • YoursDesign files, source assets and documentationFiles, assets and documentation go to the agreed design and build owners; IP, licences and handover follow the contract

06Stack

What our design work is built in

We design in Figma and agree how its specifications map to your application stack. Storybook documents coded components when that output is in scope.

Your existing designs are the starting point

We use your concepts and component library to define the remaining interface work. For a diagnosis of a live product, commission a UX audit first and use its findings to decide on the redesign.

08Industries

Industries we design for

Resource availability and workflow restrictions change which choices a screen can offer. We design those constraints into the selected flows and states, whether the user is completing a transaction or managing it.

Deepest expertise

Logistics and transportation

Order and quoting screens customers use themselves, like the order platform behind a national US moving business, where a non-technical customer selects inventory room by room and gets an instant quote without sales involvement.

Deepest expertise

Hospitality and leisure

A nightlife marketplace rebuilt to adapt to almost any new kind of venue, and a salon booking platform where two free therapists still cannot both use the one machine the booking has to respect.

Financial services

Four accessible corporate websites for a financial-services group, developed from the client's UX concepts with accessibility implementation, responsive layouts and technical QA in scope.

EdTech and training

An online test-prep platform where we improved the customer experience while the user base kept growing, on a codebase that also had to take payments.

E-commerce and online retail

A European manufacturer's seven-country storefronts, with a custom interface for the customer-service team managing the orders behind them.

Commodity trading

The smart-contract trading platform had to pull negotiation, communication and contract signing into one marketplace interface an administrator can police.

Send us the screens you need drawn, and we will say what to settle first

Bring your product brief, existing mockups and brand assets. We use the first conversation to define the interface work and whether a UX audit or a design sprint is the right first step.

Let's talk

What happens after you contact us

  1. We reply within one business dayWe identify the interface work your brief describes or ask what we need to establish its starting scope.
  2. A call about the artifact you need firstWe discuss the users and selected flows, review the designs you already own, and agree who will approve the interface and implement it.
  3. A written scope, in the order we would design itThe proposed flow sequence, research needs and design outputs, with your inputs and review responsibilities. The scope sets the screens, states and accessibility criteria we will work to.
  4. Contracts and NDAs, then a start dateThe agreement covers access, IP, acceptance and handover. Most engagements start within two to four weeks.

09Delivery

How a UI/UX design engagement works

We use design reviews to settle the selected interface behavior before you approve production screens. Engineering input helps resolve whether those interactions fit your codebase and implementation constraints.

  1. Discovery and researchWe use the agreed research to map the personas and journeys the selected flows serve. Existing findings can inform that work. From you: product goals, available research and access to users or the people who support them.You getAgreed research findings, personas and journey maps, with the information architecture for the selected flows.
  2. Structure and wireframesWireframes show the layout and sequence without finished visual styling. We review them to settle the selected flows before developing the visual direction. From you: a product owner who can resolve scope questions and approve the structure.You getInformation architecture, wireframes for the agreed key flows and a clickable low-fidelity prototype.
  3. Visual directionWe agree how typography, color and spacing express your brand in the interface. Your existing visual direction is an input to that decision. From you: brand assets, guidelines and a person who can approve the direction.You getMoodboards, one agreed visual direction, and the type, color and spacing decisions behind it.
  4. UI design and prototypingWe design production screens for the selected breakpoints and states, then test and refine the prototype as agreed. Engineering reviews feasibility; QA checks the scoped usability and WCAG 2.1/2.2 AA criteria. From you: technical constraints, design reviews and access to the users included in the validation plan.You getHigh-fidelity screens for the agreed breakpoints and states, with an interactive prototype for validation.
  5. Handover and documentationWe prepare the agreed files and specifications for the people implementing the interface. A design library and a coded library are distinct deliverables; the scope names which you receive. From you: the design and build owners, their toolchain requirements and participation in handover.You getAgreed Figma files, component-library outputs and usage documentation, handed over with the implementation owners.

12Questions

More about UI/UX design with unicrew

A UI/UX design scope sets the outputs, research, implementation input and commercial terms. Your existing concepts and component library help define what you commission.

We quote UI/UX design against the agreed screen set, research and deliverables. There is no minimum engagement period.

The estimate accounts for:

  • Screens, interaction states and breakpoints to design.
  • User research and prototype validation required.
  • Existing brand assets, concepts and component libraries we can use.
  • Accessibility criteria and implementation 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.

The design schedule follows the agreed flows, research, validation and review decisions. We estimate completion for your scope and confirm what we need from your team.

Most engagements start within two to four weeks. That is a typical start window, separate from the time needed to complete the design.

If the product direction is still undecided, a design sprint tests a concept through a prototype before you commission production screens.

Each stage produces a reviewable output for the interface you commission.

  • Discovery and research: agreed findings, personas and journey maps, with the information architecture for the selected flows.
  • Structure and wireframes: layouts for the agreed key flows and a clickable low-fidelity prototype.
  • Visual direction: moodboards, an approved direction and typography, color and spacing decisions.
  • UI design and prototyping: production screens for the agreed breakpoints and states, with an interactive prototype for validation.
  • Handover: Figma files, the selected component-library outputs and usage documentation, reviewed with the implementation owners.

We agree usability and accessibility acceptance criteria, with WCAG 2.1/2.2 AA as the scoped accessibility target. That includes deciding which screens and interactions are checked and who validates the implementation.

Color contrast, keyboard paths, focus order and screen-reader behavior require checks in the implemented interface as well as design review. A formal conformance statement belongs to the product owner; design files alone do not establish compliance.

Our ISO 27001:2022 and ISO 9001:2015 certifications govern organizational practices and do not certify your interface.

UI/UX design turns a chosen product direction into interface flows and screens. Web design applies that work to a website; a web app or mobile app also needs its application interactions designed.

Product design and development includes discovery and software engineering through launch. Web development implements the interface and the services behind it. We agree whether your purchase ends at design handover or includes implementation.

Yes. We use your existing design files, component library and engineering constraints to define the interface work.

On one training-software platform, the client already had the new components. We mapped the legacy implementations onto them, with retaining functionality as the requirement. Your engagement can likewise work within an existing library; new design components or coded components are included where the scope calls for them.

Bring in design expertise when you want dedicated work on user flows, interaction behavior and visual consistency. Your developers' interface work is a useful starting point.

We review the selected tasks with your product and engineering leads, then define the design work that supports the next release. If your first question is why users struggle with an existing interface, commission an assessment before deciding on new screens.

Yes. We work from your designer's concepts and agree the remaining design or implementation responsibilities with your team.

We implemented four corporate websites from a financial-services group's internal UX concepts. On a warehouse-software engagement, the client's designer supplied the style guide and UX concept; we implemented Angular components to her requirements, then user frontends with REST backend integration.

Bring the design files and component references. We establish which states, breakpoints and interaction specifications still need work.

Yes. We use wireframe reviews, engineering input and prototype testing to validate the selected design decisions before implementation.

A prototype lets users try a flow before it becomes production software. We agree what the test needs to establish, who participates and how findings affect the next design iteration. Engineering reviews the proposed behavior against your codebase and constraints alongside that work.

We design the selected screens against shared typography, tokens, components and interaction states, using the library your products already share where it fits.

Consistency across several products also needs decisions about component ownership and future changes. A design system covers that shared implementation and governance. We distinguish that continuing responsibility from the component outputs of an interface design engagement.

A component library provides reusable interface parts. A design system also defines shared design rules, implementation and responsibility for maintaining them.

A library or UI kit can support a defined screen set. A system is the relevant scope when several products or teams need a shared foundation and a way to manage changes. We can design within an existing library, including one you have adopted, after checking its fit with your brand and interaction requirements.

We use user research to understand the tasks your interface needs to support, then connect the findings to its flows and screens. The research plan accounts for what you already know and the questions the design needs to answer.

You provide access to users or the people who support them, along with existing findings. For a diagnosis of a live product before redesign, a UX audit is the focused first purchase.

Yes. We include engineering input in the design work and agree the review responsibilities with the people implementing your interface. That can include your existing engineers or our build team; QA responsibilities follow the agreed scope.

Our engineers work across six countries; the project managers and engineers a client works with are in four countries: Ukraine, Poland, Estonia and the UK.

We design flows, prototypes and production screens in Figma. We agree the file structure and component references with your team so the handover fits its working tools.

Storybook documents coded components when implementation is included. A Figma component library, design specifications and a coded library are different outputs; the scope identifies what you receive and any toolchain or licence requirements.

Compare the interface outputs, the engineering collaboration and the relevance of the client work. Before you commission us, we establish:

  • Which flows, states and breakpoints the screen set covers, and how you review them.
  • Who contributes implementation input and owns design approval, build acceptance and handover.
  • Which completed work matches your starting point, including supplied UX concepts or existing components.

The client quotations link to their individual Clutch reviews. Our proposal records the design and implementation responsibilities, whether your own engineers build the screens or we do.

unicrew fits when you have chosen the product or interface direction and want flows, prototypes and production screens designed with engineering context. We can develop the interface from your brief or work from concepts and components you already own.

The first conversation establishes the screen set, research needs and implementation responsibilities. You then commission the agreed design work, with software engineering included where you need it.
