About Frédéric

I have been working in the IT sector for over 20 years.

Attracted to Data, I quickly specialized in this area. To lead is to know how to measure and decide: storing, analyzing, understanding, targeting, learning, transforming raw data into relevant information, and reporting key performance indicators are all levers that define business intelligence and correspond to my skills.

Curious and based on my experience, I also enjoy taking on other roles such as Business Analyst or Senior Product Owner.
