Custom applications and software

Custom web applications and business software.

You need a tool that does not exist as such: management software that fits the way you work, a portal for your customers, an online platform. I handle the development of your custom web application or custom software end to end: design, development, production. You talk to the person who writes the code, from the first conversation to launch.

Remote, anywhere in France and abroad.

Sounds familiar?

  • Your business runs on spreadsheets that everyone edits on their own side.

  • The same information is typed two or three times, into tools that do not talk to each other.

  • Off-the-shelf software does almost what you need, but not the part that matters to you.

  • Your customers email you for things they could look up themselves.

  • You have an idea for a platform or an online service, and nobody to build it.

  • Your prototype convinced people, and you now need a real product that lasts.

What you are looking for.

Business software, customer portal, platform, SaaS: each need has its own word. Here are the most common ones, each with a real example.

How I go about it.

  1. 01

    A first conversation

    You describe your business and what costs you time. No specification needed: a few lines are enough to start.

  2. 02

    A written scope

    I write down what the application will do, what it will not, and in which order. You approve it before the first line of code.

  3. 03

    Delivery in stages

    You use a first version early, then the application grows. We adjust course along the way, not at the end.

  4. 04

    Production, and what comes next

    I deploy, monitor and document. You can keep me for changes, or hand the rest to someone else.

Custom, or off-the-shelf software?

Custom is not always the right answer. Before building, I check whether an existing tool would do the job, and I tell you.

Custom is worth it if

  • The way you work is what sets you apart, and no software respects it.
  • You pay for several subscriptions and use only a small part of each.
  • The tool must connect to what you already have.
  • You want to own it, without depending on a vendor’s choices.

Off-the-shelf is enough if

  • Your need is everyone’s need: invoicing, payroll, calendar, messaging.
  • A subscription already covers the essentials, and the rest can wait.
  • You only want to test an idea: a no-code tool can be enough for a first try.

What I have already done.

Real projects, in production. Each one gives the context and what I did.

In practice Node.js, TypeScript, Vue and Nuxt, Laravel, MongoDB and MySQL. The application opens in a browser, on a computer or a phone. Hosting is in your name.

Frequently asked questions

What is business software?
Software built for one specific activity, yours, as opposed to general-purpose software like a spreadsheet. It is also called bespoke software, or a line-of-business application. Today it almost always takes the form of a web application: you open it in a browser, with nothing to install.
What is the difference between a website and a web application?
A website presents: you read it. An application does: you log in, enter data, follow something. Many projects combine both, for instance a public site with a customer portal behind it.
Do you also build mobile apps?
My work is the web application: it opens in the phone’s browser just as on a computer, with nothing to install, and that is enough for many business tools. I have built apps installed from the App Store or Google Play before, but that was a long time ago. If that is what you need, we talk about it openly in the first conversation.
How much does custom software cost?
The cost of custom software or a custom web application depends on what it must do, and I only quote once I have understood it. What weighs most: the number of user types, the connections to other tools, and the migration of existing data. The first conversation is free, and the quote fits on one page.
How long does it take?
From one to several months depending on the scope. The application is delivered in stages: you use a first version early instead of waiting for the end.
Do I need a specification?
No. A few lines about your business and what blocks you are enough to start. I write the scope, with you, and you approve it before development.
Agency or freelance developer?
An agency brings a team, useful when design, communication and development must run side by side. With a freelance developer, you talk directly to the person who designs and writes the code: nothing gets lost along the way.
Can it connect to our existing tools?
Yes, as long as those tools allow it: accounting, online shop, CRM, payment providers. It is often the part that saves the most time, because it removes retyping.
Who owns the code?
You do. Hosting and the domain name are in your name, and the code and documentation are handed over to you. You can continue with another provider without asking me anything.
What happens after launch?
The application runs without me. If you wish, I stay on for fixes, changes and server monitoring. Otherwise, the documentation lets another developer take over.
Do you work remotely?
Yes, anywhere in France and abroad, in English or French. Conversations happen by video, and you follow progress on a live version.

Let’s talk about your project.
