About this Gig
Dashboard broken? Numbers wrong? Refresh failing? Send it to me I will find the root cause and fix it fast.
I am a Microsoft Certified Excel Expert and data analyst with 5+ years in ETL, data modeling, DAX, and reporting. I do not patch symptoms I fix the root cause and show you what went wrong.
WHAT I FIX

- Broken visuals, filters, slicers, drill-through and bookmarks
- Excel dashboards, pivot tables, Power Pivot and formula errors
- Gateway, data source and scheduled refresh issues
WHAT YOU GET
- Root-cause diagnosis, not a band-aid
- Fixed, tested file + short video walkthrough of the fix

FAQ
What do I need to send you to start?
Your file (.pbix, .xlsx, .xlsm), a short description of the problem, and what the correct result should look like. Screenshots of errors help me start faster.
My data is confidential. Can you still help?
Yes. I am NDA-friendly and can work three ways: on your file, on a masked/sample copy, or via a live remote session where the data never leaves your machine.
What if you can't fix my issue?
If I genuinely cannot fix it, I will cancel the order for a full refund. You risk nothing.
How do I know which package to choose?
Message me a screenshot or short description first. I will send a free diagnosis and tell you exactly which package (or custom offer) fits usually within 1 hour.
Do you fix Power BI Service issues (gateway, scheduled refresh, workspace)?
Yes — refresh failures, gateway configuration, credentials, incremental refresh, and dataset/report issues in the Service, not just Desktop.
My report connects to databases you can't access. What then?
We either work over a remote session, or you export a small sample/masked extract. Most logic fixes (DAX, Power Query) don't need your live source.
Will you explain what was wrong so it doesn't happen again?
Yes. Standard and Premium include a short video walkthrough plus written notes on the root cause and how to avoid it.
What if you find more problems than I ordered for?
I will flag them with a clear scope and price before touching anything extra. No surprise charges — you approve everything first.
Can you also improve the design of my dashboard, not just fix it?
Yes — visual and UX polish is included in Premium, or I can send a custom offer for a redesign after the fix.
