Build a frontend

Turn your design into a website.

The design is ready. Now navigation, forms and content need to work across devices. We build the visible interface and connect it to the intended data and processes.

One design does not show every state

The design shows short text and complete imagery. Visitors bring other cases: long names, an empty list or a lost connection. We clarify these states and build the interface so the next action stays understandable.

Use it on small screens

Content needs to rearrange sensibly. Navigation, selection and feedback are developed for narrow views and different input methods.

Work with real states

Loading, no results, success and failure need their own feedback. The interface shows only the status the connected system actually confirms.

Fictional working example

A contact form loses the input

A fictional design contains a form and thank-you page. What people see after a connection error remains unresolved.

The change

The implementation preserves entries after an error, explains how to retry and shows confirmation only after successful storage. Keyboard interaction and field errors are developed too.

How we check

The journey is tested with valid entries, missing required fields and a lost connection, followed by comparison on mobile and desktop.

What the design leaves open.

A form is submitted but no response arrives. Can the person send again? Are their entries preserved? A view of a completed form does not answer these questions. We gather the required states before implementation and agree them with the design team, so developers need not guess the behaviour while building.

We work with the existing design and technical constraints. Recurring elements are implemented consistently; on small screens, order and layout adapt to the task. Keyboard use, visible focus and clear feedback are part of implementation. The scope defines which pages, states and devices are checked.

Continue in an existing frontend

For already defined changes to an existing interface, scoped frontend optimisation is a suitable starting point.

Develop existing interfaces further.

An existing website does not need complete replacement to improve a form or product view. We first define the affected area: which components are used, which data is needed and which other pages depend on it? A small visible change can affect many places when the same element is reused. Planning needs to include those dependencies.

For a new frontend, content and backend handover are considered early. Where does text come from, what response does an API return and what happens on failure? Answering only after design creates unnecessary revisions. A scoped implementation therefore describes both the interface and its expected inputs and feedback.

How we work

From design to usable interface.

  1. Agree views and states

    We review the design and identify missing content. This produces the list of pages, mobile views and interactions to implement.

  2. Develop in the existing stack

    We use existing components and data sources. Missing backend responses are discussed with the responsible developers.

  3. Check behaviour

    Keyboard use, small screens, long content and failure cases are part of verification. Shared components are also checked in their other contexts.

  4. Hand over the change

    We document the tests and agree how the change will be released. Your team receives the information needed for later adjustments.

How we work together

Views with real content

Link to the design or describe the affected pages. Real text lengths, image formats and lists help implementation. Mark the mobile views and states already designed and those still missing.

Project and APIs

State the existing framework, CMS or shop platform. For dynamic features, sample responses and the relevant data sources help. Access is arranged through an agreed channel, never shared in the public form.

Acceptance and release

Agree who approves the design, who checks the completed feature and how changes are released. If another team will operate it, we include their code and documentation requirements.

Frequently asked questions

Clarify before starting.

Can you use a Figma design?

Yes. Beyond the views, we need information about behaviour, content and data. Open states are specified before or during the agreed implementation.

Does the website need a new framework?

We review an existing system first. The choice depends on the task, maintenance and your team's capabilities. Migration is a separate decision with its own work.

What does handover include?

You receive the agreed implementation and notes for taking it over and continuing development. Repository, test environment, release process and later support are agreed for the project.

How complete is your design?

An approved design and described features allow us to plan a new interface. For an existing page, a specific task can also be enough, such as revising a mobile filter view. That is what frontend optimisation is for.

If content and user journey are missing, start with design. If the backend does not yet supply the required data, we plan that work separately. A finished screen cannot shorten the wait for a missing API.
