I am IBM certified Blockchain developer, working at the startup and also leading Blockchain and digitalisation lab at the University.
I am trained to do presentations ranging from "typical;" scientific ones to engaging, entrepreneurial style talks.
Since I give talks about blockchain, state-of-the-art and prognosis continuously, I will be very easy for
me to make a blockchain ppt slides for your project. Usually 1h presentation, i.e. 40 - slides.
I will also give suggestion which blockchain is better for implementation of the project (Ethereium, Hyperledger and so on)
My background is science (PhD). And I am kinda starting here as a freelances, but I have expert knowledge on the topic.
