About Mamadou

With over fifteen years of experience in business intelligence, I support organizations in the strategic transformation and valorization of their data.

Throughout my career, I have developed comprehensive expertise covering the entire lifecycle of business intelligence projects: needs analysis, functional and technical design, solution deployment, and user support.

I have managed and executed numerous data projects from start to finish, combining technical mastery with business understanding to deliver reliable, operational, and directly usable solutions.

I am open to any opportunity related to data exploitation, visualization, and transformation, particularly around Power BI and Tableau technologies.
