I have a complete set of sales records that I’d like transformed into clear, decision-ready insights. Your task is to clean and model the data, then build an interactive Power BI dashboard that highlights three core KPIs—revenue trends, sales by region, and product performance. You’ll be working directly with raw exports (CSV/Excel). After shaping the data in Power Query, please create an optimized data model with the necessary DAX measures so each visual updates instantly when filters are applied. Good design is important to me: slicers for date ranges, region selectors, and product drill-downs should all feel intuitive for end users who aren’t Power BI experts. Deliverables • A fully functional .pbix file containing the complete dashboard • Brief documentation (or in-report notes) explaining data sources, key calculations, and any assumptions • A publish-ready version (Power BI Service link or PDF) for stakeholders who prefer a static view Acceptance criteria • All totals reconcile with the original source files • Each KPI visual responds in under two seconds when filters change • Layout is clean, uncluttered, and easy to follow on both desktop and tablet screens If you have proven expertise in Power BI, data modeling, and compelling visual design, I’m ready to share the dataset and get started right away.
