Hi Dumiiii thanks a lot.

Finally I have modified your reply a little bit :)

During this short tenure, he displayed his excellent professional preparation, high level skills, great personal qualities and high team spirit.

But I keep the main change :)

Thankssss again.

P.D.: I forgot to remove the person name and de company name, could I remove this thread for privacity terms?
