Hi there,
I'm a cloud architect with 10 years experience in the azure cloud. I have to admit I've not used Azure block chain, but I am well read on block chain technologies and I know the other technologies you discuss, The Azure Integration Services, as well as a lot of the rest of the platform.
As, a TOGAF certified architect I would look to provide a solution overview or proposal, to let you know what Id provide as the first milestone, to help us build some trust and deliver you some value at low risk, so anyone could continue to develop or operate the solution.
This is an area I am extremely interested in and I would be keen to work with you. Please discuss the price or bid with me. I appreciate I'm not the cheapest bid, but I am professional and experienced in this area.
Thank you for your consideration.
