    Raphael a été très efficace et très investi tout au long de cette mission dans un contexte pourtant pas facile (données complexes, intégration en production, temps limité). Jusqu'au dernier moment, il a effectué tous les ajustements demandés pour que le livrable corresponde exactement à nos besoins, et a pris soin de faire en sorte que ce livrable soit facile à prendre en main et à maintenir par notre équipe après son départ. Le tout avec le sourire et dans la bonne humeur! Je recommande vivement Raphael!

    I collaborated with Raphael for 4 months. It was intense work days, punctuated with laughter, smiles and enjoyment! A former student of College 42 armed with a strong technological and scientific culture, he always provided relevant critical insight for our technological choices. We were working on a large database aggregating flows of various types. With his great skills in data-science, Raphael developed tools allowing to integrate new sources of data within minutes. He also built an robust infrastructure to automate the data pre-processing, the training of models and the predictions delivery. All in all, he learns fast, he has great flexibility, I can only recommend Raphael!
