We created a system to mediate the settlement of cashless payments for corporate clients. We designed and implemented a scalable system from scratch. The system contained a WebService interface (REST) that easily interfaced with third party connectors.
The system can be utilized by external parties (taxi companies, travel agencies, airlines, etc) to verify whether a user has the permission to make a purchase. We automatically select which project and cost center will be charged. Processes that were previously conducted manually are now automated.
