Custom business application
Tools built around the way you work, replacing spreadsheets and double entry. I’m a freelance developer in Laval, France: I design them, build them and run them in production.
What it is
A business application is a web tool made for one specific activity: yours. It follows your rules, your roles and your documents, where a spreadsheet or off-the-shelf software forces you to re-enter data or work around it. It runs in a browser, at the office and on mobile.
Projects I can deliver

Who it is for
- A company where part of the business lives in spreadsheets, with data re-entered from one file to another.
- A team whose off-the-shelf software does not follow the rules of its trade.
- A manager who wants to know the scope and the price before committing.
