Are you serious about the name of one of your team members being called Machine Gan?
Hope this is not a joke. Maybe this is a pseudonym
What surprises you? Maybe this is the real name of the person
He works like a machine.
This is probably the most important thing. But all the same I would like to know the real name of this person?
I think this is not very important. You have already said that the main thing is that this person will do his job. And as his colleagues say, he does the work efficiently.
I think that this is quite important, because potential users and investors should know people whom they trust their funds.
In my opinion this is not the main thing. If the team performs all the required functions and does as it should be, then everyone will be happy.
