📘 Overview

This project showcases an end-to-end analysis of Home Loan applicants using SQL. The study combines technical SQL querying with business insights to understand customer patterns, product performance, and operational efficiency within a lending framework.

The analysis examines customer demographics, loan applications, sanctions, disbursals, recoveries, and delinquency trends — transforming raw data into actionable business intelligence. It demonstrates proficiency in data extraction, aggregation, and interpretation using SQL for analytical problem-solving.
