Profile Description

I help businesses turn messy data into clear reports, dashboards, and insights they can actually use.

I’m a Data & Business Analyst with 7+ years of experience, including work that identified €1.76M+ in efficiency savings. I currently work with global teams, helping them track KPIs, analyze performance, improve reporting, and turn data into better business decisions.

I can help with:

* Excel / Google Sheets reporting and automation
* Power BI dashboards and KPI reporting
* SQL data extraction, cleaning, and analysis
* Python / Pandas data processing and automation
* Data cleaning, validation, and reconciliation
* Business and performance analysis
* Financial / P&L and ROI analysis
* Recurring reports and reporting automation
* Turning raw data into management-ready insights

I'm comfortable working with large and messy datasets and can handle the process end-to-end — from understanding the business question, getting and cleaning the data, building the analysis/report, and explaining the findings.

Some of the tools I regularly use include Excel, Power Query, Power BI, SQL, Python/Pandas, Databricks, and Jupyter.

I also have a Master's degree in Data Science, which complements my hands-on experience in business and performance analytics.

If you need someone who can do more than just build a spreadsheet — someone who can understand the numbers and tell you what they mean — that's where I can add value.
