Freelancer profile translated to English.

Description

I am a computer science student (B.Sc., 6th semester) at Westfälische Hochschule Gelsenkirchen, specializing in data analysis with PostgreSQL and Power BI.

I help small and medium-sized businesses understand their data and make better decisions. My projects include analyzing an e-commerce dataset with over 100,000 orders and an HR analytics analysis based on the IBM dataset – both fully documented on GitHub.

What I can do for you:

- Data extraction and cleaning with SQL and PostgreSQL

- Creation of clear Power BI dashboards with actionable insights

- Data analysis and reporting

- Automation of Excel and Google Sheets reports

I work with both French-speaking and German-speaking clients. Reliable, punctual, and results-oriented.
