About the project

Andersen, which has an extensive talent pool of banking software development experts, was approached by a FinTech company from the EU to engineer a Banking-as-a-Service platform for their business clients in the finance industry. The project was Germany-based and lasted 11 months, relying on such technologies as Java, Spring, and React. The goal was to provide a reliable basis for the customer's clients to offer financial services via their own software. Andersen's scope of work included building an enterprise-grade app and API platform, as well as integrations with core banking systems and third-party services. The software covered the entire business cycle and incorporated KYC and AML processes.

A typical client of the resulting Banking-as-a-service solution, in this case, is an entity with its own impressive user base, which offers financial services via digital channels.
