The Challenge

The bank's credit decisions were processed through their core banking system, which returned results in 48–72 hours and had no ability to evaluate alternative data sources. Credit policy changes required IT involvement, testing cycles, and release windows—meaning the risk team was always operating on policy that lagged behind market conditions. There was no structured reason code output for declined applications, complicating regulatory reporting and applicant communication.

What We Built

We built a real-time underwriting engine that pulls multi-bureau data (CIBIL and Equifax), enriches with Account Aggregator bank statement data, applies the bank's credit policy rules, and returns an approve, refer, or decline decision with structured reason codes—in under 2 seconds. Credit policy is managed through a no-code rule engine that the risk team controls directly, without engineering involvement. Every decision is logged with a full audit trail for regulatory review.

Key Capabilities Delivered

• Multi-bureau orchestration: CIBIL and Equifax in a single decisioning pass
• Account Aggregator bank statement enrichment for income and obligation verification
• Configurable policy rule engine for credit team self-service
• Approve / refer / decline output with structured reason codes
• Sub-2-second end-to-end decisioning API under production load
• Immutable audit trail on every decision and data access event

The Outcome

Decision turnaround dropped from 48–72 hours to under 2 seconds. The credit team can now update policy rules without raising an engineering ticket—changes that previously took weeks now take hours. Regulatory reporting improved with structured reason codes on every decision. The bank's NPS on credit applications rose as borrowers received instant decisions rather than waiting days for an answer.
