Selected fintech projects

Fintechweekly badge

Our team has been involved in a wide range of fintech projects during the last couple of years. We have shaped software architectures, built custom solutions, designed APIs, developed libraries, devised payment products, integrated payment service providers, as well as ventured into crypto currencies with Bitcoin projects.

Software Architecture, Development, and Consulting

Together with the team of Payango, a provider for customizable VISA prepaid credit cards, we developed numerous software products over the course of several years. The project started with shipping a minimum viable product of an online credit card shop. Soon after, we devised and implemented a full-blown architecture of a workflow-driven, centralized service infrastructure powering several white-label systems. Payango's system was integrated with the VISA credit card network and a BIN sponsor.

SEPAone allows online merchants to accept SEPA debit payments and offers SEPA mandate management. As technology partners, we conceived as well as implemented SEPAone's entire system.

API design and product development

Skrill is a leading online payment provider offering more than 100 different payment methods across the globe.

We helped Skrill design modern APIs for merchants to integrate Skrill as a payment service provider into their own systems. Another thing we built was a JavaScript library allowing merchants to accept credit card payments without being PCI-DSS compliant. Credit card transactions could then be examined and managed in a merchant portal we helped design and build.
