This project focused on analyzing and visualizing data from a global electronics company, leveraging the full power of Power BIĀ to uncover actionable insights. Hereās how I approached it step by step:
1ļøā£ Dataset Selection:Ā I chose a multi-table datasetĀ (Sales, Customers, Products, Stores) that presented a complex structure. This challenge allowed me to showcase advanced data analysis techniques.

2ļøā£ Initial Data Exploration:Ā I thoroughly reviewed the dataset, creating an entity-relationship diagramĀ to map key connections and understand the overall data landscape.
3ļøā£ Data Cleaning and Transformation:Ā Using Power Query, I cleaned and transformed the dataārenaming columns, standardizing formats, and eliminating inconsistencies to ensure a robust and accurate data model.
4ļøā£ Calculated Columns:Ā I built custom metrics such as profit margins, delivery timelines, and customer segmentation by age, leveraging advanced formulas to enrich the dataset.
5ļøā£ DAX Measures and Dynamic Analysis:Ā I designed measures like Total Sales, Profit, Year-over-Year Growth, and key percentage metrics, enabling dynamic and scalable insights across the dashboard.
6ļøā£ Visualization Design:Ā The final dashboard included dedicated tabs for Sales, Products, Stores, and Customers, featuring interactive filtersĀ and intuitive visuals tailored for executive decision-making.
