Hi guys i am owner of some saas platform and we have a specific need about comunication between part of our system via EDI with standarized protocols. We need to build some standarded comunication endpoints for our saas application / recieve and send standarized messages to another systems (with EDI concept) Need somone who will just build methods for our backend to transform jsonModel 2 EDI standarized messages like AS2 (most popular in our region) - both side - we need endpoints to expose our methods for EDI messages (edi messages are midleware - we need some endpoint who will transform edi standarded message to some json document standard and will pass it to our messages processor English or Polish language is must have for the person who like to work with us - and voice comunication (if you cant speak clean in english but you have not problem with understand when other talks - and you ready describe good what you doing then you can still work with us - depend how good that comunication will be working for us) - we expect good comunication flow understandment - EDI formats experience is big thing - but if you are able to research them (or AS2 only) in yours cost and decide that you can deliver to us solution that fit our needs is ok too. Someone who will start work with us and deliver the job in efficient way - will be have chance for more work from us - we need one more nodejs developer for our team in general - whatever this project is just for EDI / AS2 work.
