Scalable microservice architecture to find available payment methods

We have been working with the biggest eCommerce platform in Poland and implemented an algorithm to find available payment methods. This includes 100% service availability and complex business logic based on user and product features in a huge-scale, microservice network.

Plug-and-play checkout solution compliant with PCI DSS 4.0

To let small and mid-size merchants easily integrate with international payment providers we have built a scalable and interoperable checkout service. Huge factor was placed on the security (compliance with PCI DSS 4.0) and seamless customer and merchant journey while utilizing the solution.

Integration with PayPal, Klarna, MobilePay, Shift4 and more

In order to provide as many payment methods as possible we have been developing and maintaining integrations with PayPal, Klarna, MobilePay, Shift4 and more. This includes the complexity of different setups supported and many legacy systems around that the solution needs to be compatible with.

Processing 200k rps in a marketplace of 300mln+ products

We were part of the team building a service used to classify a big scale marketplace product database for special discounts/offers etc. That included building an engine using Spark jobs run on GCP that processed the database on demand and in real-time responding to product parameters updates.
