SalesFlow

Overview

A Python + SQL + Power BI project that builds a full ETL pipeline on raw sales data and surfaces revenue trends, top products, and customer segments through an interactive dashboard.

Technical Details

Ingests raw sales CSV data and runs a Python ETL pipeline that cleans, transforms, and normalizes it using pandas before loading into a PostgreSQL database. Writes optimized SQL queries to answer core business questions — top-performing products, monthly revenue trends, customer lifetime value, and regional breakdown. The transformed data feeds into a Power BI dashboard with interactive filters for date range, region, and product category — giving a clear, data-driven view of sales performance across the business.
