NBCFDC Digital Lending Platform

🚀 AI-Powered Beneficiary Credit Scoring with Direct Digital Lending

A comprehensive Flask-based web application for NBCFDC (National Backward Classes Finance & Development Corporation) that implements AI/ML-based credit scoring with income verification for direct digital lending to backward class beneficiaries.

---

📋 Problem Statement

Challenge: Develop an AI/ML-based credit scoring model that:

1. Uses historical repayment behavior, loan utilization patterns, and repeat borrowing data
2. Integrates income level assessment using consumption-based metrics
3. Produces a Composite Beneficiary Credit Score
4. Enables Direct Digital Lending for low-risk, eligible beneficiaries

Goals:

• Ensure loans reach genuine, low-income beneficiaries with good repayment behavior
• Reduce processing time for repeat borrowers by 50% or more
• Enable same-day sanction for high-score beneficiaries
