A major financial institution needed to modernize its data and onboarding systems to stay compliant, scalable, and user-friendly. This case study shows how we turned these requirements into a future-ready microfrontend architecture.
Key Challenges and Overview
Our client set out to modernize the management of personal data and the onboarding of both natural and legal persons. The objectives were ambitious: strengthen regulatory compliance, improve customer experience, and prepare systems to scale with future demands.
To achieve this, the organization needed a microfrontend architecture – a solution requiring the design and integration of around 30 domain-specific microfrontends and microservices into one unified application. Challenges extended beyond technical complexity: each component had to fit seamlessly, deliver a consistent user experience, and integrate smoothly with existing processes without compromising performance. This project represented a strategic step to strengthen compliance, accelerate delivery, and maintain reliable, user-friendly systems for clients.
Our Approach
We carried out the project in an agile environment, ensuring continuous adaptation as requirements evolved. Our role covered the full software engineering lifecycle, from architecture design to long-term support.
Architectural consulting and technical business analysis
We began with a full assessment of the organization’s systems and processes. Together with the client, we defined the target architecture, making sure it aligned with business needs while maintaining consistency across 30 domain-specific microfrontends.
Infrastructure and build pipelines
Managing such a large architecture required strong foundations. We established standardized build and deployment pipelines, ensuring that every team followed the same process. This eliminated inconsistencies and made scaling more reliable.
Software development
Our engineers developed the frontends in React, TypeScript, and JavaScript, supported by backend services in Spring Boot and Java. This modular design allowed each component to evolve independently while still delivering a coherent, unified experience for users.
Embedded quality assurance
Testing was integrated directly into the development cycles. Continuous QA validated each microfrontend for functionality, performance, and compatibility before integration, reducing risks and ensuring stability.
Ongoing support and maintenance
Delivery was only the beginning. We continue to provide support to troubleshoot issues, optimize performance, and adapt the architecture to future requirements, guaranteeing long-term reliability.
Benefits
The new architecture delivered concrete results:
- Scalability without disruption: The organization can add new features easily and react quickly to new regulations or business priorities.
- Faster delivery cycles: Agile practices and standardized pipelines shorten development and release times.
- Reusable components: Teams reuse microfrontends across applications, reducing duplicate work and improving consistency.
- Greater stability: Teams can update or test components independently, which improves reliability and reduces system-wide risks.
