As a Data Engineer within the SMDH team at Renault, I contributed to the construction of a centralized Sales and Marketing data platform. My role was to collect, clean, and prepare data to facilitate decision-making in the sales and marketing departments. I worked closely with a multidisciplinary team, developing custom ETL (Extract, Transform, Load) in Python and PySpark to process a variety of data formats.

I also played an essential role in managing GDPR compliance for personal data, ensuring that all data was properly processed. In addition, I developed a user-friendly Web application with Microsoft Power Apps to allow Renault employees to easily access the data catalog.

My experience in this mission allowed me to work in a Cloud environment with Google Cloud Platform (GCP), to use tools such as BigQuery, DataProc, Airflow, and to set up a CI/CD environment. I also participated in data lineage and dashboarding projects, contributing to the improvement of the efficiency of sales and marketing activities at Renault.

During my mission at Natixis as a Data Engineer, I worked in the field of finance, where data management is crucial to meet regulatory and commercial needs. My role was to collect, transform, and enrich the data stored in the company's datalake.

I participated in the implementation of reporting algorithms aimed at grouping the data necessary for regulators and performing checks and corrections during data audits. My expertise in Spark-Scala allowed me to develop several treatments for the finance datalake.

In addition, I was involved in the preparation and implementation of the migration to HDP3 in collaboration with the Data Engineers of the team on different work environments (DEV, BENCH, PROD) following an Agile methodology. I also played an essential role in piloting and monitoring production flows, thus ensuring the reliability of the data used in Natixis' financial sector.

This experience allowed me to consolidate my skills in financial data management, to actively participate in migration projects, and to strengthen my ability to work in a rigorous environment subject to strict regulatory constraints.
