Achievement context describes its own base achievements and core logic, another context just describes its achievement conditions in small data classes.
• Designed and developed a secure, flexible and solid Payment system that covers transaction processes with Events and Sagas. There are over 40 integrated payment gateways like Wirecard, MasterCard, Skrill, Payvision, Pay Direct, MoneyMatrix, BlockTrail etc. The Payment internal API layer follows the open-closed principle. A Large number of segregated interfaces and core allow the integration of a new payment in short time, no matter what the payment process looks like (either one or two-step deposit, etc).
