About

French Data Engineer. Used to live in Japan (JLPT N2)
Expert in data processing (SQL - ETL - Big Data), data modeling and reporting

Did I just solve the problem you've been searching for hours online? Or did I help you with that urgent task your boss needed solved ASAP? Perhaps I even assisted with your homework, guaranteeing you a better grade tomorrow? With all the time I've saved you, now you can enjoy a well-deserved break at the coffee machine. Maybe we could share a coffee together? ;-)
