Hafed en quelques mots

Being a data scientist is not only about having the best scores, the best algorithmic skills, the best models.

Of course, it’s a part of the Job,

But It’s before ALL being able to understand the business, understand the customers you have in front of you, and being able to use all your tools (SQL, algorithms, math) efficiently to help them use the right data to solve their business problem.

Challenger, with entrepreneur mindset, I will help you to take advantage of your data to increase your profits.
