About Wandji

Coming from a rigorous background in accounting and management (BTS CG / DCG), I quickly realized that static spreadsheets and manual data entry were hindering companies' potential. Passionate about technology, I chose not to be a traditional accountant, but to specialize in Business Intelligence and automation.

Today, I apply this dual expertise to independent businesses, SMEs, and startups: I speak the language of your finance department (balance sheets, cash flow, margins) and I master the tools (Excel, Power BI, AI) to design automatic and fluid dashboards.
