About this Gig
Is your Power BI report loading slowly? Poor DAX formulas, weak data models, and overloaded visuals can seriously affect dashboard performance and I can fix it.
I specialize in Power BI performance optimization to improve dashboard speed, reduce PBIX size, and enhance refresh performance.
What I will do:
- Optimize DAX measures for faster calculations
- Restructure data models using star schema
- Improve Power Query (M) transformations
- Reduce visual rendering delays and slicer overload
- Run Performance Analyzer diagnostics
Perfect for you if:
- Your dashboard loads slowly
- Your PBIX file is too large
- DAX measures are timing out or inaccurate
- You inherited a messy report
- You need a fast professional dashboard
What you will get:
- Optimized PBIX file
- Summary of fixes applied
- Before/after performance comparison
- Free revision if needed
I am an experienced Power BI expert focused on clean DAX, efficient models, and scalable reporting solutions.

FAQ
What do you mean by optimization?
Optimization means improving report speed, accuracy, layout, KPIs, and overall business usability so decision-makers can clearly understand performance.
What file do I need to send you?
Send your .PBIX file. If it contains confidential data, you can replace the data source with a sample dataset, the structure, DAX measures, and data model are what matter for optimization, not the actual data values.
How much faster will my Power BI report load after optimization?
It depends on where the bottleneck is. DAX rewrites and star schema conversions typically reduce load times by 50–80%. Visual layer cleanup alone often cuts 20–40%. I'll give you a realistic estimate after reviewing your specific file — message me before ordering and I'll take a look for free.
What if the report doesn't get faster after your changes?
I offer a free revision. If the performance issue turns out to be infrastructure-related (for example, a gateway, Premium capacity, or server-side problem) rather than the PBIX itself, I'll tell you clearly, explain what's causing it, and help you understand the next steps even if that's outside t
Will you explain what changes you made, or just send back a fixed file?
Every delivery includes a written summary of every change made and why it helps performance.
