FAQ
What do you need from me to start?
Your data file or database access details, plus a short note on what KPIs/questions the dashboard should answer. Sample/anonymized data is fine.
Can you connect directly to my database?
Yes: SQL Server, MySQL, Excel, CSV and API data sources, and others via gateway. If you can't share access, an anonymized export works too.
Do I get the source file?
Yes, the .pbix file is always included, in every package.
Can you fix or improve my existing report?
Yes — slow performance, refresh errors, and DAX issues are my specialty. I can review your .pbix file, fix DAX, improve the data model, clean Power Query steps and optimize performance. Message me first so I can scope it.
Do you sign an NDA?
Yes, happy to work under your NDA before you share any data.
Can you optimize a slow Power BI report?
Yes. I can tune DAX, reduce unnecessary calculations, improve relationships, simplify Power Query and fix query folding issues.
Should I contact you before ordering?
Yes. Please send your data structure, current problem and expected result so I can confirm the correct package.
