I'm machine Engineer (5 Y process )
I can design any machine with CE sign ( DTR , Drawing , test )
I'm able manage small team 20 -30 people
I am still trying to get my head around machine engineer typically engineering is divided into civil, mechanical and electrical.
Mechanical engineers are certified in their country of origin to ensure things meet safety specifications. If you were a mechanical engineer in poland I can't see how you could possibly believe this complete garbage because you would have to know how to do the calculations properly so buildings and bridges didn't collapse.
It appears Machine engineer is the Polish version of what some professions do here in USA like garbage collectors call themselves Waste Engineers. So I take it you are like a CNC operator and nothing like a mechanical engineer.
When I google machine engineer it gives me mechanical engineer and it was doing my head in how any mechanical engineer could actually believe your rubbish because they need to pass certification exams to be able to do the calculations properly.
As I said you can dribble this rubbish till you die no scientist or engineer is remotely going to be interested in it.
Anyhow I will leave you to your junk.
