With my expertise in data engineering, I can assist you in extracting valuable insights from your data, providing you with a competitive edge in the marketplace.

I have been the first data guy of a french startup company located in montpellier caller Waalaxy. I designed and built an ETL using MongoDB and Stripe as the primary data sources, and Redshift as a data warehouse using Airflow and Python scripts. Implemented a FastAPI-based API to retrieve financial metrics such as MRR, LTV,

and retention rate, and developed web-based dashboards to effectively monitor and report on these metrics.

I have also been a data engineer for a Big consulting firm called Sopra Steria. The mission was for Carrefour. I worked on Carrefour’s request tickets. Standardized data analysis with a Python library and improved collaboration with a GitHub repository. Designed a PostgreSQL data warehouse for reporting and ML workloads. Engineered a data pipeline using Apache Airflow and Python scripts to transfer incident data from CSV files to SQL tables.

I studied at a french Grande Ecole d'Ingenieur called Arts et Métiers ParisTech where I did lots of different things. Some of them were statistics, computer science and algorithms and machine learning.
