Meet Summaiya

1 following

I'm Summaiya — a freelance Power BI developer and data analyst based in Karachi, working remotely with clients across the Gulf, Europe and North America.

I turn scattered data — Excel files, ERP exports, SQL databases, Google Sheets — into Power BI dashboards that leadership actually opens on Monday mornings. Currently building the reporting layer for Gulf General Contracting Company (GGCC), Riyadh — 7+ construction sites, one consolidated view of project progress and operations.

MY STACK
Power BI · DAX · Power Query (M) · SQL · Advanced Excel · Python (pandas) · Figma

MY APPROACH
Before I open Power BI, I ask three questions:
1. Which decision will this dashboard help you make?
2. Who opens it, and how often?
3. What does "good" look like as a number?

Everything after — the data model, the measures, the visuals — is just plumbing to serve those answers.

WHAT YOU GET
End-to-end delivery. Documented data model. KPI dictionary. Video walkthrough. And a report your team can maintain and extend after I'm gone.

READY WHEN YOU ARE
Send me a note about what you're trying to measure, and I'll come back with how I'd build it and a realistic timeline.
