Data Analyst

Amsterdam, Netherlands

Data Analyst

I've worked in data analysis for 6 years, for small e-commerce shops that need clarity from scattered spreadsheets and CRM exports. I work in Python (pandas) for processing and Power BI or Google Data Studio for visualization, chosen based on what the client can maintain themselves. I start from the decision the business needs to make, not from the chart. I don't build machine learning models — that's a related but separate specialization. A typical project is an audit plus one working dashboard, five to seven working days.
