Efficient deployment of an instant credit payment system

A leading provider of digital payments and credit solutions in Poland wanted to launch a new payment method that offered instant credit approval in its online store.

To make it work, the company needed infrastructure that could process requests quickly, scale with demand, and keep costs under control. It also had to handle major traffic spikes without affecting the customer experience.

A Darize consultant joined the project as Cloud Architect and DevOps Team Lead and they:

• Built a cloud-native architecture on Microsoft Azure using autoscaling AKS (Azure Kubernetes Service) clusters that automatically responded to traffic spikes.

• Enabled instant credit scoring with machine learning models that assessed customer eligibility in just five minutes, much faster than traditional banking systems.

• Optimized costs and availability by scaling infrastructure based on demand, especially during high-traffic periods such as SMS marketing campaigns.

The infrastructure created by the Darize consultant helped the client launch and scale the new payment method while maintaining reliable performance and operational efficiency.

As a result, the client gained:

• A scalable, resilient infrastructure that adapted to changing customer demand.

• Fast credit decisions and uninterrupted service, even during peak traffic periods, and a better customer experience.
