Description

I am a BI & Talend Freelance Designer Developer with over seven years of experience in designing and optimizing ETL flows to support business performance. I assist my clients in their data transformation projects by building reliable, automated, and scalable integration solutions.

Specialized in Talend (Open Studio & Cloud), I work on the entire decision-making chain: data collection, processing, storage, and restitution using tools like Power BI or Qlik Sense. My expertise also covers Informatica, SSIS, SQL, Java, as well as PostgreSQL, Oracle, and SQL Server databases.

Autonomous and rigorous, I easily integrate into existing teams and prioritize clear, results-oriented communication. My priority: to deliver simple, high-performance, and sustainable solutions that are perfectly aligned with business needs.

If you are looking for a Talend and BI expert to industrialize your data flows, modernize your decision-making system, or manage your integration projects, I would be delighted to collaborate with you.
