Work on the full implementation of a data architecture for a new factory, from the definition of all the tables needed to be created in our cloud warehouse (on Snowflake) with an ELT tool (Matillion) to the different visualization tools that had to be created with PowerBI from these tables.

Deployment of connected sensors in our factories, optimization of their data transmission to a SQL database

Project of identification of genetic markers from tumor classification on gene expression data :

- Reduction of dimensionality through PCA applied to genes expression
- Representation of the genetic data as heatmaps
- Binary classification (with or without tumors) with a CNN
- Work on the interpretability of the classification with gradCAM algorithm to identify genetic markers
