Freelancer profile translated to English.

Description

Graduated engineer in Big Data & Data Science, I design and industrialize robust and scalable data pipelines on Azure, AWS, and Databricks environments, for major players such as ENGIE IT, Microsoft, SNCF, and Chanel.

I work on the entire data value chain: ingestion, transformation, modeling, exposure, and data governance, up to the delivery via Power BI and Tableau decision-making dashboards. My expertise covers Python, SQL, and Spark, with a strong DevOps (CI/CD, DAB, Terraform) and Agile culture.

Accustomed to collaborating with business teams, I support needs framing, workshop facilitation, and presenting results to management.
