Architecture

Built for reliability,
designed for scale

A layered, event-driven architecture that handles the complexity of banking integration so you do not have to.

System Layers

Six layers of banking infrastructure

API Gateway

Unified REST API entry point with authentication, rate limiting, and request routing.

Process Engine

BPMN-compliant workflow orchestrator with stateful execution and compensation.

Service Layer

Business logic modules — accounts, loans, transactions, reconciliation.

Integration Layer

Adapters for BankOne, Finacle, NIBSS, and third-party services.

Security Layer

AES-256 encryption, RBAC, audit logging, and compliance tooling.

Infrastructure

Multi-tenant deployment on Azure with auto-scaling and 99.9% SLA.

Design Principles

Engineering decisions

  • API-first: every feature accessible via documented REST endpoints
  • Event-driven: loosely coupled services communicating via domain events
  • Multi-tenant: single codebase serving multiple institutions with data isolation
  • Stateful workflows: long-running processes that survive restarts and failures
  • Horizontal scaling: add capacity without re-architecting the platform
  • Zero-trust security: verify every request, encrypt every payload
