Freelancer profile translated to English.

Description

Passionate about data and analysis, I help companies transform their data into useful indicators for decision-making.

During my experiences at Camif and Assurance Maladie (CNAM), I worked on reporting, data analysis, data development, and integration. I notably participated in the implementation of decision-making reporting to track national activity and key business indicators.

I mainly work on:

• Creating Power BI dashboards

• Data analysis and KPI definition

• SQL queries and optimization

• Automating processes with Python

• ETL and data integration

• Decision-making reporting and piloting support

What my clients generally appreciate: my ability to quickly understand business needs, to be autonomous, and to propose simple, reliable solutions adapted to project challenges.

Whether you need a dashboard, a one-time analysis, automated processing, or data structuring, I would be delighted to discuss it with you.

See you soon,

Wassim Benkhelifa
