Hi, I’m Sabina.

I work on the whole thing, not just how it looks.

The data, the model, the DAX and the report your team actually opens. My career took a few turns before data, and working alongside one of the best people in the Power BI field reshaped how I think about the whole stack.

From the data model to the last pixel.

I’ve delivered reporting for finance, controlling, sales, marketing and operations. Usually it starts with the data, then the people, then the report.

Data & models

Star schema and semantic models with hundreds of millions of rows, data analysis in SQL and clean DAX. A good semantic model is the foundation everything else stands on.

Performance tuning

Slow reports usually start in the model. I optimise semantic models and measures, find the bottlenecks and fix them, so pages load in seconds and the numbers stay right.

Setup & governance

Workspace setup, licensing and source-controlled development. Certified in Microsoft Fabric (DP-600), so your reports fit in when Fabric is part of the picture.

Report design

Layout, custom visuals and theming, so a report reads in seconds and looks like it belongs to your company.

How a project usually goes

First
I dig into the data

What’s driving the numbers and what’s worth tracking at all.

Then
I talk to the people

What decisions they make, what they need to see and what they rely on today.

Finally
I build it right

A solid model underneath and a report on top that people actually open.
