Building Gateway Processes using X Platform from Neeve Research for Supplier API's

We are looking for several resources(6-8) to build gateway process using Neeve Research's X Platform for our supplier gateways in a new B2B exchange. (The X Platform requires full stack JAVA and XML skills.)

Each API will take roughly 30-40 hours to complete based on our experience doing this before.

I have 30-40 new Supplier APIs to get set up and tested.

I would suggest you do the following to get a solid idea of the effort for pricing and to make sure you can use the process/tools involved:

1. Setup your development environment - we use eclipse as our IDE, and X PLatform has a useful video for starting this process. It can be found here: [url removed, login to view]

2. Have a quick look at this sample webinar for building microservices using X Platform: [url removed, login to view]

Build out the X PLatform sample starter app located here: Note: While doing this starter application, you will be asked to generate an X Platform License and download/build from GitHub.

3. Review this sample API: [url removed, login to view]

4. Review the Mechanics of invoking the API

5. Review the API so that you have a basic functional understanding of the API flow and data model.

If you were actually building this one out- the next step would be to map these APIs to my supplier gateway API. You would need to learn the canonical structure of the supplier gateways and the associated Maven archetype using which a new supplier gateway would be bootstrapped.

For the selected freelancer, we will provide a walk thru of using the framework we have set up and the Supplier API Certification before you start the work. You will be given a number for SMS or pgone calls, along with an email to use for support/questions etc. your during the building of these gateways.

Each resource you have working on this will need to sign an NDA.

Please bid on a price per Gateway Process for each API that will be provided.
The one provided is a sample.
Please let me know the number of resources that you have available since I would like to have more people working on them to get them done as soon as possible.
