About this gig

Need help with a Power BI report that shows incorrect totals, confusing visuals, or filters that don't behave as expected?

I'm a Senior SQL Server DBA / Data Engineer with 10+ years of experience across SQL Server, data integration, and reporting, including hands-on Power BI experience.

I can help with:

Fixing DAX measures and calculations

Correcting visual, slicer, and filter behavior

Improving existing report layouts

Building a single report page using your prepared data model

Please message me before ordering. Describe the issue, share the expected result, and provide screenshots or a sanitized PBIX file so I can confirm the scope and package.

Each package includes the updated PBIX file, a brief explanation of the changes, and one revision within the agreed scope.

Complex DAX, data model redesign, ETL, gateways, refresh infrastructure, and Power BI Service deployment require a separate quote.

Please remove confidential data and credentials before sharing files.
