Data Science Portfolio

Lucas Brossier

Data Scientist at IMREDD (Université Côte d'Azur).

About

A data engineer turned data scientist: after apprenticeships at Datalyo (data engineer) and Groupe ARA (developer), I now design and deploy profiling and scoring models for IMREDD (Université Côte d'Azur), from data preparation through to turning business needs into data solutions. I hold a Master's in data engineering from EPSI Lyon (where I also chaired the student union and served as the school's national ambassador), and I enjoy building reliable pipelines as much as making data understandable for the teams who use it.
