FinTech Platform With Microservices

How we built the most scalable online banking platform with Microservices 

The Story

Our client is a banking platform provider which means that the core system is being used by numerous banks across the globe, serving millions of customers. It was started more than five years ago and faces typical problems of rapid expansion: lack of platform scalability and disorganized development processes.

As it usually happens, these problems lead to an inability to land and serve more customers, to maintain the quality of service, to effectively respond on customer’s demands and, after all, putting most of the resources on the regular maintenance instead of further development. Situations like this prevent companies from growth and reaching new heights making the platform too expensive to maintain and expand, sluggish to innovate and, finally, to lose all of the competitive advantages.


The platform in our case was built using the outdated technologies and, worst of all, with the system architecture being a complete mismatch with the business requirements.

The Solution

We were able to turn the tide and, after completion of business and technical review, there was a solution to meet all of the requirements.

The new banking platform is now built using the microservices approach, where there is no single back-end system to handle all operations and, instead, it was split with multiple services that handle all core functions. This architecture solves one of the core problems our client faced with - product scaling.

Being used by Uber, Netflix, Linkedin and many other rapidly growing companies it proved to be a good solution to address the scalability issues. Special attention to security was paid as well, the system by its architecture is PCI compliant which means that it can effectively deal with all the threats related to data storage, processing, encryption and the secure communication.

The Outcome

  • Highly-scalable system that can be expanded and maintained with 60% less resources required.

  • Reliable back-end on top of AWS using the microservices architecture.

  • Secure and PCI-compliant solution.

  • The platform can serve more customers while being faster and more reliable.

  • Can be crafted to meet demands of more clients with less coding work involved.
