With the involvement of mobile and microservice solution architects, we managed to create a well-scalable solution that can be implemented on a general platform. The mobile application itself is built on a cross platform framework; the backend is microservice based. During the requirements exploration phase, it became clear that a web-based admin interface would also be needed, where advisors could review their clients and where superusers could modify the value sets used in the public application (e.g., list of banks or banking products). After designing the CD/CI process and agreeing on the basic data models, work could start in parallel on the three components of the system. Team members were in daily contact to avoid any integration issues and had a dedicated project manager who could identify these potential points.
