About Ruben

Looking to leverage your data in a useful and actionable way? Want to set up dashboards to define an action plan? Want to understand your customers' behavior and optimize your offering?

I will support and advise you from start to finish to address your strategy & data challenges:

1) Data Analysis & Visualization: To analyze your performance, I will set up clear, precise dashboards using visualization tools (Tableau, Power BI, Excel).

2) Data Strategy: To define an optimal data strategy, I will advise you on how to best leverage your data sources.

3) Data Science Projects: To maximize your impact, I will use data science techniques (machine learning / deep learning) to develop an effective solution for your data challenges.

With a double background in management from HEC Paris and a scientific background from École Polytechnique, I am passionate about data analysis.

As such, I conducted a study on the distribution of bonuses (profit-sharing & incentive) within the 120 largest companies in France. This study was notably the subject of an article in Les Echos and was featured on the France 2 television news.

I also have experience as a Data Scientist consultant in a strategy consulting firm, where I assisted clients in leveraging their data to define an optimal marketing strategy (Marketing Mix Modeling).

I would be delighted to help you with your data & strategy projects.
