Client Context: Crédit Agricole Indosuez manually produced its pricing simulations without a centralized tool to manage client rates. Bankers could not quickly simulate new rates by portfolio or client, which slowed down negotiation and revenue optimization.

Expertise and Tools: Talend Data Integration, SQL Server, Qlik Sense, financial data modeling, SQL optimization, business needs assessment, user training.
Results: Real-time pricing simulation operational. Tool adopted daily by sales teams for negotiation and banking revenue optimization.
