Project overview

Andersen took on the challenge of creating a finance tool for GBank – a digital finance organization based in Georgia. Our goal was to build two native mobile apps for iOS and Android that would provide GBank's clients with a quick, seamless, and convenient experience. These apps offer all the features one could expect today. It is possible to get authorized remotely, open and manage accounts, deal with cards and loans, use QR codes for finance purposes, and more.

In order to modernize GBank's IT infrastructure, we expanded their existing resources using AWS Cloud and adopted an IaC approach for resource management. This ensured increased flexibility, simplicity, and convenience in allocating new environments and resources. Additionally, our solutions encompassed the implementation of the BPM Corezoid engine for business logic. It provided for the advanced capabilities mentioned above.

Throughout this 12-month project, we worked closely with GBank to prepare the requirements and the design and ultimately achieved the successful implementation of the MVP functionality. As a result, the GBank mobile app is now poised to attract small and medium-sized enterprises as new clients.

IT architecture context

The customer has two data centers for the app. In order to scale their resources, update processes, and use innovative solutions, we decided to expand existing resources via AWS Cloud. Before the start of the mobile banking app project, an investigation process showed that the company used a classic approach to infrastructure management. All new resources were allocated manually through the operations team. The app was deployed in manual mode to dedicated virtual servers for each environment.
