Data Analyst
Detail-oriented Data Analyst specializing in transforming messy, raw business data into clean, reliable, and decision-ready reporting. I help clients clean and organize datasets — removing duplicate records, fixing missing or inconsistent values, standardizing date/text/number formats, and correcting broken formulas and calculations — so your data is accurate and easy to work with.
Skilled in Excel, PostgreSQL, Power BI, Python, DAX, and SQL, I build efficient data models, clean DAX measures, and calculated columns for metrics like Total Revenue, Total Orders, Average Order Value, Profit, and Top Products. I organize data into structured Excel tables and PivotTables, then deliver polished, interactive dashboards with slicers, filters, and dynamic drill-downs — whether as an executive-ready Power BI (.pbix) model or a fully editable Excel dashboard with clear charts and a summary sheet.
I've supported sales, inventory, customer retention, and regional/monthly performance analysis, connecting data sources and translating business requirements into actionable insights. I communicate clearly, explain what was changed and why, and support ongoing reporting needs and dashboard maintenance for long-term engagements.
