• Advanced DAX programming; Power Query (M language).
• Power BI Desktop and Power BI Service; Oracle and SQL Server environments.
• Experience with Power BI administration, gateways, RLS/OLS, governance, and capacity management.
• Relational and dimensional modeling concepts; ability to translate tech concepts for non-technical audiences.

Responsabilités

• Design, develop, and optimize Power BI semantic models using best-practice dimensional modeling techniques (star schema, snowflake, dataflows, shared datasets).
• Build enterprise-grade datasets with proper relationships, hierarchies, calculation groups, and incremental refresh.
• Collaborate with data engineering teams to define data requirements, improve data quality, and ensure model scalability and maintainability.
• Implement data modeling standards that support self-service analytics and governed data access.
• Develop complex DAX measures, calculated columns, and tables to support business logic, KPIs, and analytical insights.
• Optimize DAX for performance, readability, and maintainability across large datasets.
