Our Germany - based company provides a payment API that unifies the APIs of numerous "Payment Service Providers" (PSPs) around the world. This way merchants can make use of different PSPs in different countries to accept various payment methods without changing their implementation.
The communication between our system and the PSPs is done through so-called "adapters". They translate between methods from our Java SDK and the PSP webservice operations. Many of them are already in place. They are written in Java and hosted by us.
Now we are looking for a freelancer with Java and web API experience (ideally in the field of online payment) to create a new adapter for us. We are looking for freelancers, not companies, to build a personal relationship. So far we successfully worked with people from Eastern Europe and Middle East so these are our preferred regions.
This project is supposed to start in early February 2016. We are looking for somebody who can do this project full-time (40 hours per week), or at least close to full-time. We estimate 4 weeks of implementation time, but it can be less or more, depending on the project. We will provide the PSP documentation, test account and intensive, continuing guidance to our system.
If this project works well, we would like to continue the relationship and hand out an extension of this project and other, similar projects to you in the future. We are interested in a personal, productive long-term relationship.
If you are interested, please let us know so that we can get to know each other better. We would be happy to hear from you.
