• Description We need someone to set up an AS4 endpoint for receiving B2B messages and sending them using C#. You will be given various documentation to start with. For security reasons, I may have to keep the production private key myself, so you may have to work remotely on a machine. • Bidding Your bid is my budget. If you deliberately put in a low bid to attract me to speak to you, you either revise your bid, or I will ignore you. • Delivery We need the source code and will integrate your program into a much larger one. You will be paid once you finish all the work and it works on my machine. We will also attack your program, as it has to be secure and reliable without loopholes. It has to be bug-free. • Platform Your code has to work on Windows. • Workplace You will be working online remotely. • Experience Please show us your detailed related work experience and portfolio. Without similar experience, you are unlikely to be awarded, as you may not finish the project anyway. • IP The intellectual property, including the source code, belongs to Sors Markets Ltd. • Interview We may interview you to see if you can work on the project. • Demo We will need to do a demo on Freelancer. If you have any questions, please send us a message. • Further work More work may need to be awarded to the winner.
