Thank you for your kind words, could you tell me which grammatical points are incorrect so I can improve? Thanks!

Also the me should be an I, and listed after the others. Though to be honest, most people make the same mistake. Your English is at the level where you can pass off as a native from an English speaking country so I would not worry too much. Everyone has at least a few mistakes in almost everything they write.

thank you both, of course "companies/company" was just a distraction while "I/me" is due to the fact that many times in Italian you can swap them (maybe it's not perfectly correct in Italian too but for spoken language it's ok)

The only error worth mentioning is "last companies has failed". It must be either "company has failed" or "companies have failed".

Good luck!
