I have been wrangling with data for over a decade. I consulted for over 500 brands, agencies, governmental organizations and NGOs, in many industries: automotive, cosmetics, entertainment, healthcare, telecom, FMCG, … from SMEs to Fortune 500 companies.


Data is my passion, and I update my knowledge on a daily basis, getting hands-on experience on data science processes and any new best practice. But to me this goes beyond the mere data analysis, advanced statistics, developing effective machine learning algorithms or creating data products. It’s my in-depth knowledge of the many industries I worked with, and the many, many challenges of each staff member I got to empathize with, that lead me to conjure raw data into actionable data. Don’t mistake me for a wizard though. It’s the mix of a data scientist with real-world professionals that makes the wizardry happen.

This is why I believe not just in educating, but rather in empowering my clients by bringing to them sophisticated concepts in a business-oriented and realistic manner. They can leave the geeky details to their friendly-neighborhood data scientist, but they are the experts, they’re the ones taking decisions and sticking their neck for them, and data will be only as good as they can understand it and act on it.

I’m a French national living in Berlin, Germany, able to handle projects in English, French and German. I often travel worldwide to meet my clients for scoping and delivery meetings.

My missions are centered around data science projects and social listening strategies, with a strong focus (but not only) on Natural Language Processing.

I’d love to hear about your projects and give you my recommendations on all the possible approaches, so don’t hesitate to get in touch.
