About Atmane

I support companies, managers, and operational teams on short Excel assignments, focused on reporting, dashboards, and performance monitoring.
My goal is to transform complex, unclear, or non-existent Excel files into simple, reliable, and immediately usable tools, without over-engineering.
I intervene in particular on:

Audit and simplification of existing Excel files
Rapid creation of Excel dashboards (KPIs, activity monitoring, customer performance)
Implementation of automated monthly reporting
Data structuring and validation

The deliverables are designed to be understandable by end-users, usable without extensive training, and adapted to operational constraints.
Pragmatic, results-oriented approach, with clear and actionable deliverables.
