  • Data Modeling & DAX (Power BI): Built a dedicated Date Table on a 1-to-many relationship with sales records, then authored DAX measures for Total Revenue, Total Transactions and Total Quantity Sold with interactive Date, Month and Quarter slicers.
  • Dashboard Visualizations: Designed visuals tracking monthly revenue trends, item-wise sales, payment-method distribution (Cash, Credit Card, Wallet) and Order Type split (In-store vs Takeaway).
