Case study · NBFC Lending

A compliance-grade NBFC lending platform delivered on a 6-sprint UAT cadence.

We engineered a custom Loan Origination + Loan Management platform for Unnatti Finserv with a configurable BRE, e-mandate and penny-drop flows wired in, and RBI Digital Lending Guidelines and DPDP Act controls embedded across origination, servicing, and reporting.

Challenge

The starting state.

Every product or workflow change required vendor involvement — nothing was self-configurable. New loan variants, fee structures, or approval stages meant paid change requests with a weeks-long queue.

Credit rules were hardcoded. When underwriting policy needed to change — tighter bureau cutoffs, new deviation rules, product-level exceptions — the system didn't follow without a full engineering engagement.

Loan origination workflows were fixed in code. Adding an approval stage, a document checkpoint, or a compliance step meant raising a ticket, not making a configuration change.

Our approach

How we engineered it.

Compliance-first architecture

RBI DLG, DPDP, and IT Outsourcing constraints baked into the LOS schema, cloud topology, document service, and disbursement state machine, not bolted on at audit time.

Policy-aware workflow design

Multi-stage deviation workflows and a credit review committee surface engineered into the underwriting flow, with AA-driven bank statement analysis and offer generation tied back to the same audit trail.

Sequenced migration

Stood up new platform alongside legacy, mirrored disbursements for parity, sunset legacy origination per loan product without disrupting servicing.

Productized accelerators

LOS module skeleton + adapter library for bureaus, BSA, eKYC, eSign, and payment rails, compressed a 12–18 month vendor timeline into 8–16 weeks.

Senior ownership

Architects in the UAT room, integration contracts reviewed before code, failure modes named before QA found them, production support through first 90 days.

What we built

Architecture and the systems it talks to.

API-first, event-driven LOS with DPD tracking as a first-class event consumed by collections and GL in real time

Multi-stage deviation workflows with configurable approval tiers, exception rules per product, and full deviation history retained for audit

Credit review committee surface with case file aggregation, deviation log, and decision evidence tied back to the underwriting trail

AA-driven bank statement analysis as a first-class underwriting input, sitting alongside Perfios and Finbox in the analysis layer

Offer generation engine producing eligibility-bound offers with expiry, customer acceptance log, and amendment trail

Cooling-off periods modeled as state transitions in the disbursement engine, audit-logged per change

KFS document service emitting regulator-format documents with versioning and customer acceptance log

Borrower data localization via cloud topology aligned to RBI residency clauses

Immutable audit log per loan, queryable and replayable for inspection

Outcomes

Quantified impact.

6-sprint

Compliance-grade UAT cadence

Formal sprint-to-sprint UAT with audit-traceable acceptance per release.

11 blocks

RBI + DPDP rules implemented

Across origination, servicing, collections, and reporting modules.

Missed disbursement windows

Zero servicing disruption during sequenced migration from legacy LOS.

Real-time

DPD tracking

Days past due tracked per account; collections queue updated on each payment event, not overnight.
