Über Zahra
I help companies turn their data into actionable insights. My focus is on structured data analysis using SQL and Python, as well as the development of clear, decision-relevant dashboards in Power BI and Tableau. I work analytically, reliably, and solution-oriented, supporting in particular with data preparation, KPI definition, reporting, and BI projects. Ideal for companies that need short-term analytical support or want to make their data more transparent and usable.
