About this Gig
Is your Power BI dashboard running painfully slow, showing incorrect numbers, or failing to load? A poorly structured data model or a bad DAX calculation can break a dashboard's credibility and frustrate users. As an experienced Business Intelligence developer, I will restructure your data model and optimize your DAX measures to ensure your reports are lightning-fast, accurate, and scalable.
Whether you need complex time intelligence calculations, a complete overhaul of a flat table into a proper Star Schema, or performance tuning for heavy datasets, I am here to help.
What I Can Do For You:
- DAX Optimization & Creation: Write and optimize advanced DAX measures (YTD, YoY, rolling averages, complex filters, and rankings).
- Data Model Restructuring: Convert messy tables into a high-performance Star Schema (fact and dimension tables) following Microsoft best practices.
- Performance Tuning: Diagnose slow-running reports, reduce model size, and optimize query performance.
- Debugging & Troubleshooting: Fix incorrect totals, context transition issues, and circular dependencies in your formulas.
- Best Practices Review: Code review and refactoring for your existing Power BI file (.pbix).

FAQ
What do you need from me to get started?
our Power BI file (.pbix) or a sample of it, along with a clear description of the issues you are facing or the new measures you need.
Can you make my slow dashboard load faster?
Yes! I specialize in reducing model size, removing redundant columns, and optimizing DAX/Power Query steps to speed up rendering times.
What if my calculations are showing incorrect totals?
This is usually due to evaluation context or relationship misconfigurations. I will fix the filter context and ensure your aggregations are accurate.
Do you build the visual layout as well?
This gig focuses strictly on the engine room (Data Model & DAX). If you need full dashboard UI/UX design, check out my main dashboard gig or contact me for a custom offer!
