Freelancer profile translated to English.

Description

Senior Consultant specializing in data technologies.

My technical expertise primarily revolves around SQL, Python, Snowflake, Tableau, and Power BI. I also master a wide ecosystem of Data and BI tools such as Power BI, Databricks, dbt (cloud & core), Dataiku, and BigQuery.

During my assignments, I have developed solid experience in data migration, BI architecture optimization, and dashboard implementation. Recently, I have acted as a Senior Analytics Engineer on complex issues, ranging from migrating SQL Server sources to GCP BigQuery via dbt, to improving data quality and migrating dashboards (from Tableau to Power BI).

Beyond technical skills, I am proficient in project management and place great importance on team training to strengthen their autonomy and the effectiveness of their analyses. I have had the opportunity to support clients in various sectors, including non-food Retail, Luxury, Telecommunications, Banking, and Media.

Feel free to contact me to discuss your data projects!
