Since 2013, we have been involved in projects with Norwegian companies building mobile payment systems; mCash, Auka, and Vipps. Our involvement have mostly been on the backend, working on core transaction and settlement logic as well as internal and external APIs.
When working on payment systems, the concepts of data consistency, idempotent operations, and fault-tolerant operations need to be well understood. In order for the system to perform well under load, it is required to understand the relevant performance characteristics of the system including e.g. modern cloud infrastructures.
Through the years, we have built domain knowledge within the field of mobile payments that we now can apply with existing and new customers working on problems in the financial sector. The technologies we have applied in this field are mainly Python and Go, deployed on the Google App Engine and Azure stacks. Both relational and document database models have been used.
