Enterprise Core Banking for a Gold Loan NBFC — Finance case study

The challenge

Monolithic systems couldn't scale. The NBFC needed a platform to:

  • Manage end-to-end lending
  • Support multi-branch expansion
  • Handle high transaction volumes
  • Integrate many third-party systems
  • Ensure compliance and auditability
  • Enable future AI capabilities
  • Run on enterprise on-premise infrastructure

We delivered consulting, architecture, backend engineering and AI enablement.

How it works

A core banking microservices ecosystem

Independently scalable services, connected through an event-driven architecture:

  1. 01

    Customer, loan, liability, asset and auction management services

  2. 02

    Payment processing, financial accounting and workflow management

  3. 03

    Rule engine, audit & compliance, and document management

  4. 04

    Notifications, reporting & analytics, third-party integrations

  5. 05

    User and access management with role-based control

What we built

Key capabilities

01

Modern backend platform

Java, Spring Boot and Spring Cloud running distributed microservices.

02

Purpose-built data layer

PostgreSQL for transactions, MongoDB for analytics and reporting.

03

Event-driven by design

Apache Kafka real-time events, async inter-service communication, scalable workflow orchestration.

04

Enterprise security

OAuth 2.0, OpenID Connect, Keycloak identity management, RBAC and end-to-end encryption.

05

Full observability

ELK stack, Prometheus and Grafana across every service.

06

Hardened deployment

High availability, disaster recovery, backup and failover, security hardening, regulatory compliance controls.

Business impact

What it changed

Digital core modernisation

Traditional siloed systems replaced with a modern banking foundation.

Independent scalability

Critical functions scale on their own — no more monolith bottlenecks.

Operational efficiency

Automated workflows reduce manual intervention across lending operations.

Regulatory readiness

Audit, compliance and access control built in, not bolted on.

Future-proof technology

AI-ready architecture adapts to emerging fintech requirements.

Enterprise reliability

Engineered for mission-critical, always-on lending.
