Project Overview
Our partnership with ING delivered a modern, scalable platform that powers their digital banking services across 40+ countries, serving millions of customers daily.
The Challenge
ING's customer requests, and campaign management systems were built on legacy services with outdated technologies that limited scalability and agility. The bank needed to transform these critical customer-facing systems while ensuring compliance with strict financial regulations and maintaining 24/7 availability. The existing services struggled with handling peak loads during campaigns and onboarding processes, creating bottlenecks that affected customer experience and limited the bank's ability to quickly adapt to market changes.
Our Solution
The solution involved a phased migration strategy that replaced the legacy customer requests, and campaign management services with modern, independent microservices. A customer-facing frontend was developed to streamline the onboarding process. The architecture utilized containerization with Docker and orchestration with Kubernetes to ensure scalability during peak campaign periods. A robust CI/CD pipeline enabled frequent, reliable deployments while maintaining the strict security controls required for financial data. The new system architecture provided the flexibility to scale individual components independently based on demand.
Technology Stack
Our solution for ING leveraged modern cloud technologies and microservices architecture to create a scalable, secure platform that powers their digital banking services and internal operations.

Azure DevOps facilitated the CI/CD pipeline, enabling automated testing and deployment of new features with minimal risk.
