About me


Since June 2016, I work as Data Scientist at Homly You, a Saint-Gobain subsidiary.

I would rather define myself as a type-B data scientist, meaning I like to build robust solutions that go in production. And, let's be honest, quite often the v0 includes no machine learning, and the v1 requires only long-terme averages. But my strong mathematical background allows me to follow the needs and work afterwards on more complex solutions.
