We are looking for an expert for long-term business relationship. The first project deals with passing a GUID string from one database to another database. Our client has member that signup for our training. They are put into the clients database and then passed to our training website database via a GUID which populates the training database. Then the member is able to sign in to the clients website and their login and profile are passed to the training database and they are automatically login. This technology is all completed, but somehow it has broken and needs to trouble tested with the clients IT department, thus you will be working as an extension of our company. Communication skills in English are very important, please do not bid if you do not speak good English and have a excellent team skills.

Once this issue is fixed there will be additional ongoing projects.
