A growing e-commerce firm requires a highly skilled data visualization expert to develop an interactive dashboard using Tableau or Power BI. The dashboard will aggregate sales data from three distinct sources, presenting key metrics like monthly revenue growth, customer acquisition cost, and product profitability. Key functionalities will include dynamic filtering by region and product category, and drill-down capabilities for individual sales representatives. The project timeline is 4 weeks, with an expected delivery of two fully functional, secure dashboards and comprehensive documentation. Candidates must demonstrate prior experience with complex data integration and possess strong SQL skills for data extraction and transformation.
