• Build reliable batch (and where relevant streaming) data pipelines using Fabric Data Pipelines, Dataflows Gen2 and integration with Azure data services.
• Model data for analytics use cases in Power BI (star schema, semantic models) and for advanced analytics in Lakehouses.

Ingest, transform & govern data

• Ingest data from APIs, flat files, on‑premises and cloud databases, and SaaS sources into OneLake / Lakehouses.
• Implement clear and testable transformation logic (data quality checks, deduplication, SCD, CDC, business rules) using Notebooks, SQL, Dataflows Gen2 or Warehouse features.
• Apply data governance best practices (workspaces, roles, sensitivity labels, lineage, RBAC) across Fabric.

Collaborate with Data & AI teams

• Work closely with data analysts, analytics engineers, data scientists and BI developers to make data discoverable and usable.
• Expose data to end‑users through Power BI datasets, semantic models and reports built on top of Fabric.
• Support advanced analytics / ML workloads by preparing and structuring data within the Fabric environment.

Operate & optimize

• Set up CI/CD and deployment pipelines for Fabric assets (Power BI, Data Pipelines, Notebooks, Datasets) using tools like Azure DevOps or GitHub.
• Monitor and optimize data pipelines, storage and workloads for performance, reliability and cost.
• Help define and implement best practices, coding standards and reusable components for Fabric within the team.

Contribute to the Data & AI community

• Actively share knowledge within the Belgian and Dutch Data & AI community at adesso (brown‑bag sessions, internal talks, blogs, PoCs).
• Contribute to proposals and pre‑sales activities, helping shape new Microsoft Fabric engagements.
