Web application

Your idea turned into a tool built for you.

Are you losing time every week on a spreadsheet that has outgrown itself, or a string of steps done by hand? I build a simple tool, shaped around the way you work, that takes care of the repetitive jobs for you.

What it actually is

A tool you open straight from your browser.

No need for a fancy word. A web application is a tool you open in your browser, just like you open a website, on a computer or on a phone. Nothing to install, nothing to update: you log in, and everything is there.

The difference with a website is that it does more than simply present you. It does something for you: it organises, it calculates, it sends alerts, it keeps all your information in one place for your whole team.

Let's talk about what you need
Is it the right choice?

A custom tool is made for these cases.

Let's be honest: a custom tool only makes sense if you genuinely have work to simplify. Here is how to tell the difference.

It's for you if

  • You repeat the same steps every week in a spreadsheet or on paper.
  • Your information is scattered around and you would like it to live in one single place.
  • Several people need to see and update the same information at the same time.
  • Off-the-shelf tools never quite fit the way you work.

Keep it simpler if

  • You mainly want to present your business and be found: a showcase website is plenty.
  • An existing tool on the market already covers your need without costing you anything more.
  • Your need fits on a contact page or a simple form: we can handle that on a website, much faster.
What's included

A complete tool, built to last.

I don't hand over an empty shell to fill in later. The tool arrives ready to use, and made to stay with you over time.

Where do we start?

Tools I have already designed and put online.

To be concrete, here are three applications I built myself, from the screen you see right through to where the information is stored. Not ideas on paper: real tools, genuinely online.

A quote and invoice tool

Built for a company in Geneva. You create and keep track of your quotes and invoices, with smart assistance that reads documents and fills in the fields for you, and accounts protected by a password. The information is kept somewhere safe, all in one place. An internal tool, so there is no public link.

CVGenius, a CV builder

An online tool for putting together your CV from five templates, with your own account and a payment system built right into the tool. Online and very much real.

CoverCraft AI, cover letters

An assistant that writes your cover letter on its own, from your CV and the job advert, drawing on smart assistance that understands and writes text the way a person would. Here too, payment is handled right inside the tool.

These three show the range of what I can do, from the small tool to the full application: the screen, the place where information is stored, built-in payment, and smart assistance. Yours will be designed around your real need, at a fair price, with no agency rates, and as close to you as possible, on both sides of the border between France and Switzerland.
How it works

We take the time to scope it well, then we build.

A custom tool is won at the start, above all. The more precisely we pin down your need, the better the tool fits. Here is how it goes.

01

We scope the need

We look together at what takes up your time today and at what the tool needs to do, in detail.

02

We design the tool together

I show you what the screens will look like before building. You approve, we adjust.

03

I build it in stages

The tool takes shape piece by piece. You test each stage on real situations.

04

We put it into service

We get it up and running for good, I support you along the way, and we keep improving it from your feedback.

How much it costs

A price set on your project, not an off-the-shelf rate.

A custom tool isn't sold as a fixed package, because no two are alike. The price depends on what the tool needs to do. Here is how it works.

I price it according to what the tool needs to do.

The more the tool does for you, the more work it takes: that is what sets the price, not a ready-made grid. You describe your need, and once we have scoped it together, you receive a clear, detailed quote. What is written down is what you pay.

We can also start small, with the essentials, then add the rest as we go. All in euros for France or in francs for Switzerland.

A tool project in mind?

Every tool I build is shaped around a specific need: I never start from a ready-made shell. You can judge my eye for detail and finish on the applications above as well as on my website work: it is the same standard everywhere.

The simplest thing is to talk it over. Tell me what is costing you time, and I will give you my honest opinion on whether a custom tool is worth it in your case.

Frequently asked questions

What people often ask me

Is a web application like a mobile app you download?
No, and that is rather good news. There is nothing to download or update. You open the tool in your browser, just like a website, on a computer or on a phone. Everyone always sees the latest version, without doing anything.
How long does it take to build a custom tool?
It depends on everything the tool needs to do. We often start with the essentials, a first usable version fairly quickly, then add the rest in stages. We set a timeline together as soon as we have scoped the need, so you know what to expect.
Will I be able to develop it further later on?
Yes, and the tool is built for that from the start. We begin with what is most useful, then add new features as your needs grow. You are never stuck: the tool grows with your business.
Is my data safe?
Yes. Access is reserved for the people you choose, each with their own login. Your information is kept somewhere safe and stays yours. We talk it through together so it suits what you handle.
Do I need to install anything?
Nothing at all. A browser is enough, the one you already have on your computer and your phone. You log in, and the tool is there, wherever you are.

What if a custom tool gave you your hours back?

Tell me what is costing you time. I get back to you in person within 24 hours, with an honest opinion and a clear quote, with no commitment.
