I will optimize your slow power bi dashboard and cut refresh time

Is your Power BI report slow, bloated, or taking forever to refresh? I fix underperforming Power BI and SSAS models so your reports load fast and your team gets answers, not spinning wheels.

I hold a Master's degree in Statistical Sciences and have redesigned a 550M-row enterprise data model, cutting refresh time from 2 hours to 25 minutes. I know where Power BI performance problems actually come from and how to fix them.

What I look at:

- Data model structure (star schema, relationships, granularity)

- DAX measures and calculation logic

- Power Query steps and query folding

- Aggregation and incremental refresh strategy

Depending on the package, you get a written audit report, hands-on optimization of your existing model, or a full rebuild with aggregation tables and incremental refresh plus a walkthrough so your team understands what changed and why.

Message me with a quick description of your current setup (data source, model size, current refresh time) before ordering, so I can recommend the right package.
