What we bring

A tool that works the way you do.

Off-the-shelf software asks you to adapt to it. A custom application does the opposite: it takes your rules, your roles and your tools, and makes them run together.

Your rules, not a vendor's.

Your steps, your approvals, your exceptions: we write them into the application exactly as you practise them. Nobody has to work around the tool to get their job done.

Everyone sees what concerns them.

Management, team, client: one tool, access tuned precisely for each.

  • Dashboard
  • Records
  • Invoicing
  • Settings

Plugged into your tools.

Payments, accounting, email, calendar: the application talks to what you already use. No more retyping.

Your data stays yours.

A structured database, backed up, exportable at any time. The source code and the access are handed over to you.

It grows with you.

A new need, a new team, ten times the users: we add a module, we don't start over.

Behind the scenes

What sits under the screen.

The interface is only the visible part. An application stands on four layers — we design and build all of them, so they hold together.

  1. What your teams see

    Screens, forms, dashboards: drawn for how you work, consistent from the first to the last.

    • React
    • Design system

  2. What applies your rules

    Calculations, validations, automations, access rights. The brain of the application, written for your business.

    • TypeScript
    • API

  3. What the application knows

    Clients, records, history: a structured, reliable, backed-up database.

    • PostgreSQL

  4. What keeps it online

    Hosting, security, monitoring. Available and fast, day and night.

    • Cloud edge
    • Monitoring
Deliverables

What you get

  • Product framing and user journeys

    Before the first line of code, we set down in writing what the application does, for whom, and in what order we build it.

  • Interface and design system

    Every screen designed, plus the component library that keeps the whole coherent as the application grows.

  • Back end, database and API

    The engine: your data and your business rules, ready to talk to your other tools.

  • Authentication, roles and permissions

    Secure accounts and finely tuned rights: everyone reaches what concerns them, nothing more.

  • Deployment and documented handover

    The application live, the source code, the access, the documentation. All handed over to you, and explained.

Stack & technologies
  • TypeScript
  • React / Astro
  • Node
  • PostgreSQL
  • Cloud edge

Indicative — the final stack is chosen to fit your project.

The right fit

Is this the right approach for you?

We don't sell the same answer to everyone. Here is when this approach is the right one — and when another will serve you better.

It's the right approach if…

  • Your spreadsheets and current tools no longer keep up with your business.
  • Your business has rules no off-the-shelf software respects.
  • Several profiles work on the same data, each with their own rights.
  • You are launching a SaaS product and want to master every detail of it.

Look instead at…

Unsure between two approaches? We settle it together, at the framing stage.
