Hi, I'm Dalbert, an Insights/Analytics Engineer from Finland.

End-to-End Microsoft Fabric solution with Git Documentation

Skills: PySpark, SQL, DAX, Power BI, Medallion Architecture, ETL.

Business Impact: Identified 81,744 MWh in recorded efficiency risk, translating technical waste into €4,904,640 of avoidable costs.

Key Achievement: Engineered a real-time "Single Source of Truth" that maintains 102.59% heat self-sufficiency while tracking ESG targets across a diverse energy fleet.

By leveraging DirectLake, I bypassed the traditional 'Import' vs 'DirectQuery' trade-off, allowing executive users to see massive energy load changes instantly without the overhead of scheduled refreshes.
