About Ngambi

Business Analyst & Power BI Expert. I support companies in valuing and translating their data into strategic decision-making tools.

Thanks to a hybrid profile combining solid technical expertise with a global vision of management and commercial challenges, I don't just create charts: I design tools that speak to your business teams and boost your performance.

My areas of intervention on Power BI:

- Data Preparation & Modeling: Cleaning (Power Query), structuring databases, and writing optimized DAX formulas.

- Data Visualization: Creation of dynamic, aesthetic, interactive dashboards focused on user experience (UX).

- Business Intelligence: Design of tailor-made reports for sales monitoring, operational management, and complex KPI analysis.

Why work together?

Responsive, structured, and attentive, I quickly adapt to your ecosystem to transform your raw data lines into clear action levers. Whether for a one-time need or complete automation of your reporting, let's discuss your project!
