Hi, Manfred! How are you? I am Maksim from Zhytomyr, Ukraine (UTC +2)
I do not want to speak a lot about our amazing experience I just want to say we have enough implemented projects in the blockchain.
We will be happy not just start the implementation but also help you to do proper business analyze, design specification or prototypes, do testing and fixing, support the system in future since we are covering Full Life Cycle for the projects.
Best Regards,
Maksim
