Data Analyst: Power BI, SQL and Python

Über mich
I turn messy, inconsistent business data into reports you can actually trust.
I'm a data analyst working with Python, SQL and Power BI, specialized in cleaning and standardizing sales data from real-world sources — spreadsheets, PDFs, XML and ERP exports. I've built automated pipelines and audit routines covering 60+ retail clients, catching reporting errors worth hundreds of thousands of dollars.
Send me a sample file and I'll tell you honestly what can be automated and what can't. Clear communication, documented rules, delivery on time.
