The challenge

The bank’s system depended on a commission-based payment gate from a global financial institution, which set conditions that made it harder for the business to pursue a European expansion.

The client’s cloud team faced a fixed deadline from the board that left no time to recruit additional developers for the job. There was also the concern that the expanded team might have to be disbanded after the project.

The product also needed a credible system architect that could design the infrastructure under strict EU banking regulations. All of this made the company source for a development partner.

Partnership goal To transform a traditional bank into a truly European financial institution with growth empowered by cloud computing services

Before

The bank wanted to expand onto the cloud, but a third-party pay gate limited the choice of currencies and the number of countries a transfer could go to

After

Our joint team unblocked the bank’s technology growth by creating a completely new payment process based on reliable AWS services

The Software House hand-picked professionals who joined our partner's team under a hybrid model

We worked on

Team formation

The bank’s cloud division required more Frontend/Backend developers on board.

The Software House filled the talent and knowledge gap in weeks where the company would have needed months to do so. The line-up included 2 QA Engineers, 12 Developers, 3 DevOps, 2 Product Designers, an Architect, and 2 Project Managers.

They joined our partners ranks under their PO’s leadership, but also worked directly with technology leaders from the Cloud, Testing, and Salesforce units, and with business analysts.

Our partnership

In half a year, our joint team established the bank’s very first cloud infrastructure for transaction processing, which was then integrated with the legacy system and the process for observability.

Because developers worked with pre-built components, the company prepared just in time to get a SEPA certificate, which added dozens of new countries customers can transfer to.

Technology choice

React (frontend), Node (backend), Typescript, AWS services, Serverless, Terraform, Scali (analytics) + Python (data analysis), Mambu, Salesforce.

What our partner achieved

The Software House’s architect mapped out a new infrastructure to implement the payment gateway. We used Amazon S3 for storage, Form3 for payment processing that enabled the use of all SEPA services, and Mambu as a ready-made engine with a range of banking services. This first phase took 6 months.

The new cloud setup allowed the client to check all the boxes needed for a SEPA certificate, issued by the European Payments Council only a few times per year, which the project team secured.

With the SEPA certificate, the bank offered customers transfers in Euro across Europe’s 36 countries, where such were previously limited to the Netherlands, Germany, and Austria.

Two months into the project, the company asked The Software House’s developers to build a new retail banking platform for the Dutch market. A small group of early adopters then tested the platform.

Together with our partner’s developers, we proceeded to build the website and the client’s web app for registering deposit accounts.
