Description

Data & Cloud BI Expertise (13+ years)

Specialist in the design and industrialization of decision-making platforms, I support companies in building reliable, scalable, and performance-oriented Data solutions.

With a background in on-premise MSBI (SSIS, SSAS, SSRS, SQL Server), I am now driving the convergence towards the Modern Data Stack with complete mastery of the Microsoft ecosystem.

🚀 Microsoft Fabric & Azure Specialization

I work across the entire value chain to build modern architectures:

Microsoft Fabric: Implementation of OneLake, Lakehouse, Data Factory, and DirectLake.

Azure Data: Synapse, Azure SQL, Data Lake Storage (ADLS Gen2).

Power BI: Advanced modeling, complex DAX, governance, and security.

💰 Added Value: FinOps & Performance

In a Cloud environment, cost control is critical. I integrate a native FinOps dimension into my interventions:

Capacity Optimization: Precise sizing of Fabric and Power BI Premium F-SKUs.

Technical Efficiency: Optimization of flows and queries to reduce resource consumption.

Monitoring: Implementation of tracking dashboards to prevent budget overruns.

🛠️ Tech Lead & Architect Role

Migration: Securing the transition from MSBI to Azure / Fabric.
