Web & mobile development

The right tool for the way you work.

An internal application, a customer portal or a new service: we design the journeys, develop the interfaces and connect them to your information systems. The first objective is a clear tool that meets a specific need and can evolve.

Let’s discuss your needs
Real situations

How this can
help you.

  1. 01

    A business application that brings requests, supporting documents and approval steps together so everyone knows what to handle and where to find information.

  2. 02

    A customer portal showing the information and actions available to the signed-in account, designed for both users and service administrators.

  3. 03

    A mobile-friendly web experience for viewing or entering information in the field, with connectivity, phone features and synchronisation needs assessed.

A scope defined together

What we build
with you.

  • A definition of priority journeys, user roles and the features selected for the first version.
  • Mock-ups or a prototype to discuss screens and interactions before finalising development.
  • An application and its integrations, with the functional and access checks agreed for the project.
  • User and operational documentation, alongside the deployment materials included in scope.
Our approach

Move forward with
a clear direction.

01

Define a complete first journey.

We identify users, what they need to achieve and the information required at each step. Edge cases matter too: incomplete requests, input errors and unauthorised actions. We choose a coherent first journey to build a useful version without immediately multiplying features.

02

Design the interface and connections.

Mock-ups help verify that screens and sequences of actions are understandable. In parallel, we examine available APIs, data formats and authentication options in your existing tools. These findings shape the architecture and clarify what can be connected, adapted or replaced.

03

Develop, verify and hand over.

Features are developed and tested against the agreed journeys. We consider loading states, errors, keyboard navigation and the screens people use. Deployment and onboarding are prepared with your team, with clear arrangements for the agreed fixes and future changes.

Before you begin

Your questions.
Our answers.

Is a mobile application always necessary?

It depends on the use case. A responsive web application can support many journeys. Specific phone features or offline use need further assessment. We choose the platform after clarifying those constraints and distribution requirements.

Can you work on an existing tool?

We begin by examining available code, dependencies, data and operating conditions. This helps distinguish straightforward improvements from larger changes. The aim is a justified scope that accounts for people already using the tool.

Can we launch a small version and add to it later?

Yes, by choosing an initial version that meets one need from start to finish. We clarify its limits and the feedback to collect after launch. Later features can then be guided by observed use and the architectural constraints identified at the outset.
