Olivier Leroy

I have been a data analyst and BI consultant since 2008. I create your dashboards, collect and organize the data to be integrated, manage the project's progress, and define potential areas for improvement. I have worked on over 20 analytical projects in 15 years, sometimes on 20-day assignments and sometimes on assignments lasting several months. The majority of these projects were for CAC40 companies, but I also help several startups establish their data culture at a lower cost.

The data visualization and reporting tools I use most often are Qlikview, QlikSense, Tableau, PowerBI, and Excel.

I have developed data quality methodologies that allow me to achieve the set objectives while controlling planning risks.

Digital transformation is my passion; I define myself as an evangelist and am particularly fascinated by the societal impacts of digitalization. I teach data visualization and data quality in the Big Data specialized Master's program at ESCP, as well as an introduction to the data age in the MS Strategy and Organization.

For some long-standing clients, I have a more comprehensive role as a data strategist, which involves developing the entire value chain from raw data to refined information. This requires alignment between business strategy, available data, and new technologies, primarily data science and big data. When this role exists internally, it is titled Chief Data Officer.

I would be delighted to help you quickly implement your decision-making and predictive tools.
