Client’s goals

Currencycloud was looking for a reliable partner with the strong technological expertise to extend its engineering capabilities and cooperate on the development of the payments platform. N-iX engineers received the task to create a secure and flexible web application with a simple-to-use but feature-rich online interface on the basis of the Payment Engine.

Additionally, the team had to enhance the existing version of API and overall functionality of the company services including core banking, payments, customer-facing features etc.

  • Legacy system modernization and its support to guarantee error-free operation;
  • Optimization of the internal platform services to ensure their security, fast delivery, and decreased downtime;
  • Development of Currencycloud Direct app within a short time frame to enable the client to showcase the solution during Finovate conference;
  • Ensuring the security of the platform and its compliance with a number of fintech regulations.

At the initial stages, the team was involved in the development of a white-label UI application Currencycloud Direct powered by the Payment Engine. This feature-rich online interface provides the customers with a simple and transparent way to manually make or track payments thus accelerating their speed-to-market. Moreover, the updated version of API allows the customers to customize their workflows and automate their entire international payment processes.

After the successful completion of the first iterations, Currencycloud decided to extend their cooperation with N-iX specialists on the maintenance of their existing services and development of new ones. Our programmers contributed to the legacy system modernization, introduced new features into existing services and ensured smooth operation of the platform. The team paid special attention to strengthening the security of Currencycloud platform, ensuring its compliance with industry regulations.
