Résumé

After an education and a few experiences in BI, I opened up to new challenges by working on projects focused

on Data. I then quickly got interested in Big Data technologies and their applications.

Aside from working on those technologies, I keep myself up to date through MOOCs and technical events

(organized by IT communities). Most of those stick around data science as it lets me combine both the

technologies and the machine learning algorithms
