About Nessim
J'aide mes clients à transformer leurs données en outil de pilotage fiable.
J'interviens notamment lorsque :
- vos chiffres clés vivent encore sur des Excel fragiles
- vous avez un CRM et des outils en place, mais aucune vision fiable pour piloter
- vos process de reporting sont manuels, lents et source d'erreurs
Concrètement : tableaux de bord (Tableau, Power BI), fiabilisation de vos flux (SQL, Snowflake, BigQuery), automatisation de process manuels (n8n, Power Automate), analytics Salesforce/CRM.
Ma différence : je ne livre pas des slides et des recommandations, je construis l'outil qui tourne. Et j'embarque vos équipes pour que vous restiez autonomes après mon départ.
