The Challenge

KBZ Bank needed to modernise their digital banking infrastructure to serve millions of customers with reliable mobile banking, secure payment gateway integration, and a CI/CD pipeline that ships features rapidly without compromising financial security or regulatory compliance.

ObjectivesWhat we set out to achieve

Deliver a high-performance mobile banking application for retail and business customers

Integrate a secure payment gateway supporting MPU, Visa, and Mastercard

Implement an automated CI/CD pipeline for rapid, safe deployments

Ensure 99.97% uptime and PCI-DSS compliance

Our ApproachDiscovery, Design, Architecture & Development

Step 1Discovery

An extensive 8-week discovery phase involving stakeholders from retail banking, corporate banking, payments, compliance, and IT operations to map requirements, regulatory constraints, and integration points with existing core banking systems.

Step 2Design

Designed a multi-tier architecture with a React Native mobile application, Node.js API gateway, secure payment processing layer, and automated CI/CD pipeline with staged deployment environments including sandbox, staging, and production.

Step 3Architecture

React Native cross-platform mobile application communicating with a Node.js microservices backend. Payment gateway with MPU, Visa, and Mastercard integration. Jenkins pipeline with Docker containers and Kubernetes orchestration. PostgreSQL for transactional data with read replicas for analytics.

Step 4Development

An 18-month engagement with the team working in 2-week sprints. Initial 3 months focused on mobile application foundations and API gateway, followed by payment integration (months 4-9), CI/CD pipeline automation (months 10-12), and security hardening, performance optimization, and regulatory compliance (months 13-18).
