Background
About Mariusz Krause
I specialize in transforming raw data into clear, actionable insights that support strategic decision-making and operational improvement. My daily toolkit includes SQL, Databricks, Python, and spreadsheets—alongside ETL development and process automation using Google Apps Script, VBA, and JavaScript. I believe that good data work is not just about analysis, but also about clarity and accessibility. That’s why I focus on building streamlined dashboards in Tableau or Looker Studio that help teams act, not just observe. My goal is always to increase efficiency, reduce manual work, and make data a practical asset across the business.
