Description

As a data engineer specializing in data science and Big Data with Scala, Python, and Spark technologies, I am passionate about end-to-end data development and processing.

I have carried out two main missions:

the first mission consisted of improving order processing and also ensuring data quality at Orange.

My second mission was at Colissimo with the objective of processing data based on an event-driven system for delivering packages,

calculating weights, and predicting package delivery times.

I also participated in architecture design, application deployment, production releases, and performance testing.

Rigorous, organized, and with excellent team spirit, I am capable of successfully completing any project in a deployment environment.
