I will fix your power bi dax measures, data model and slow reports
Ali Raza
About this gig
Is your Power BI report slow, showing wrong totals, or full of DAX errors? I can fix it.
I have 4.5+ years of experience in business intelligence and data modeling, and I work with Power BI, DAX, Power Query and SQL every day.
What I fix:
DAX measures: wrong results, filter context problems, time intelligence (YTD, last year, month-on-month)
Data model: relationships, star, snowflake and galaxy schemas, many-to-many and bidirectional filter issues
Performance: slow refresh, heavy visuals, large model size, Power Query query folding
Report clean-up: measure organization, naming, row-level security
How it works:
1. You send the PBIX file (sample or dummy data is fine) and describe the problem
2. I review the model and send a short summary of what I found
3. I fix the issues and explain every change so your team can maintain it
Please do not share confidential or personal data. Anonymized samples work well.
Message me with a short description of the problem before ordering, and I will confirm the right package.

Which Power BI versions do you support?

What if you cannot fix the problem?
I will tell you before starting if the request is outside what I can deliver, so you do not order the wrong package.
Do you work with live database connections?
Yes. I can connect Power BI to live databases and RDBMS using secure access and custom SQL queries.

Please message me before placing your order for urgent requests, and I will do my best to accommodate your timeline.
