Architecture Executive Summary

Mobile-first borrower intake funnel, Pan-India pincode B-Tree indexing engine, Document AI neural statement parsing, Fastify lead routing gateway, and real-time WhatsApp triggers.

1. Frictionless Borrower Intake & OTP Authentication

Borrower drop-off occurs when intake forms exceed 3 steps. We design a 3-step mobile-first onboarding flow with phone OTP verification and interactive EMI sliders that captures borrower intent in under 60 seconds.

Key Architectural Rules:
  • Phone OTP verification eliminates fake spam leads immediately.
  • Pre-qualification sliders provide instant borrowing estimates to keep applicants engaged.

2. Pan-India Pincode Serviceability & Employer Categorization

Our platforms index Pan-India pincodes with composite database indexes to cross-reference multi-bank serviceability lists in under 10ms. Employer prefix search matches applicants across Cat A, B, C, and D lender tier lists instantly.

3. Document AI Statement Parsing & Underwriter Console

Borrowers upload PDF bank statements and salary slips. Document AI parses multi-page transaction tables in 5 seconds, calculating average balances and salary credits automatically for executive review.
