Power BI Analytics

Interactive dashboards for marketing, sales, RFM analysis and operational control.

Overview

I turn fragmented spreadsheets and sources into a clear data model, a focused set of KPIs and an interface where teams can see performance and opportunities quickly.

Problem

Large spreadsheets explained what happened, but required manual preparation and made it difficult to understand causes or compare segments.

Solution

For each project I defined business questions, cleaned and connected the data, built DAX measures and designed a visual hierarchy from the main outcome down to product, time and segment detail.

Lessons learned

A strong dashboard does not show everything. It creates a path from the important signal to its cause and supports a specific decision.
