01 / THE STARTING POINT
A price is a promisethat has to stay true.
Batiprix has been the French reference for construction estimating since 1983, published by Groupe Moniteur within Infopro Digital. Its library holds more than 30,000 ouvrages, each priced from labour time, hourly rate and materials: the déboursé sec.
From 2023 to 2025 I led the JavaScript department, taking its tools from conception to deployment.
02 / THE PRODUCT IN PRACTICE
From a yearly spreadsheet to a living library.
One workspace behind every number.
A React dashboard replaced the Excel workflow: supplies, materials, ouvrages, companies and settings in one place, edited by the people who answer for the prices.
One codebase, web and Windows.
Clients read the same library in the browser or on the desktop, from one React and Electron codebase.
03 / A CLOSER READING
Two databases,one daily sync.
An internal base where prices are prepared, a client base where they are read, and a synchronization between them every day, with caching and load balancing in front.
Nine lots and twenty-three trades travel that path every day.

04 / THE THROUGH LINE
Keep the number honest,every month.
An estimate is only as good as the price under it. The work was making sure that price was read, checked and delivered on time, and that nobody had to type it twice.
