About Atmane

J’accompagne les entreprises, managers et équipes opérationnelles sur des missions courtes Excel, orientées reporting, tableaux de bord et suivi de performance.
Mon objectif est de transformer des fichiers Excel complexes, peu clairs ou inexistants en outils simples, fiables et immédiatement exploitables, sans sur‑ingénierie.
J’interviens notamment sur :

Audit et simplification de fichiers Excel existants
Création rapide de tableaux de bord Excel (KPI, suivi d’activité, performance client)
Mise en place de reportings mensuels automatisés
Structuration et fiabilisation des données

Les livrables sont conçus pour être compréhensibles par les utilisateurs finaux, utilisables sans formation lourde et adaptés aux contraintes opérationnelles.
Approche pragmatique, orientée résultats, avec des livrables clairs et actionnables.
