We are looking for a highly experienced developer with advanced design skills or access to a highly advanced design team. We are requesting proposals for a Blockchain as a service Platform that functions similarly to IBM's Blockchain Labs on Bluemix. If you are unfamiliar with it you can create a free test account on Bluemix and follow the instructions to access the Blockchain Labs Devops section. Essentially what it is, is taking open source Blockchain code from github and running it on a cloud instance so it can be spun up at the click of a button. User creates VM -> triggers node to deploy -> blockchain can then be customizable and rest API exposed. More documentation is available by looking at IBM's docs about their Blockchain as a service platform. We are using that as an example because it is similar to what we want developed. Please submit your qualifications, examples of your work, and what questions you have.
