Fabien in a few words

Data scientist / engineer depuis 2 ans (MASTER software engineering), j'ai réalisé de nombreux projets autour de la data autant du coté database, ETL pipeline que du coté analyse et data science .

J'ai travaillé pendant 1 an et demi chez Qobuz en tant que data scientist , j'ai réalisé de a à z plusieurs modèles prédictifs afin d'aider à la rétention, conversion des clients et détection de fraude et pour alimenter une data warehouse complète. (+5 à 10% de rétention supplémentaire suite à la mise en place de mes modèles)

J'ai également de l'expérience en web (API, architecture) et plusieurs année de développement en C , C++

• Data scientist:
o Model for predicting Churn (Tensorflow, keras) (65% accuracy)
o Model for predicting client’s conversion (from trial period to subscribed) (70% accuracy) and around 3-7% improvement in retention.

o Persona for clients , every new clients get predicted a “Persona” based on historical clients which is used to calculate a more accurate LTV / ARPU
