I am not your blockchain guru or expert

9 years ago i did some mining on a personal computer. Loved the idea. The bitcoins are somewhere. I do not know.
2 years ago i downloaded the ethereum software and created a raspberry pi powered blockchain node. The node worked relatively well (there were no stable light clients at that time).
Now i am launching worlds first medical device using ethereum and IPFS and a js stack. It is stable as hell, user friendly and the customers (hospitals) really like the interface and concept.
Does that make me an expert or guru?
Hell no. I know how to use and implement blockchain technology, and know how to communicate/share it with other people. I also have some knowledge about the legal implications. It's more like pioneering, being a rapid prototyper than being an expert.
It is my enthousiasm about decentralisation that i want to share. The true experts are at the core of the beautiful software. The bitcoin and ethereum (and many more) developers. They don't wear a suit, they do not give powerpoint presentations 24/7. They are not contibuting to the hype.
They create beautiful products, truely know how encryption and decentralisation works and share it with the community.
Give them credit, they are the true disruptors.
PS Here is my prototype. An ethereum node using geth/nodeJS and Trezor. Fully open source, and available soon on Git.
