About Pierre

I help companies make their Excel tools reliable, automated, and simplified when they become critical to the business.

Coming from an accounting and management background, I work on complex files used daily: activity monitoring, steering, controls, reporting, or automation of repetitive tasks.

My approach is primarily business-oriented and pragmatic: understand the real need, define a simple and robust solution, then automate what truly saves time and secures data.

I mainly support SMEs, firms, and administrative structures that want to reduce errors, improve the readability of their tools, and regain peace of mind in their processes.

Each mission is defined, delivered with a maintainable, documented solution adapted to real-world usage.
