Hi!
My name is Luis and I am Portuguese, which means I speak Portuguese fluently. I have been traveling around the world speaking English and I live in an environment where I mainly speak English, since my work environment includes people that are non-Portuguese and we speak in English all the time. Also, my wife is not Portuguese and our communication is done in English.
I also studied English in British Council, a very well known school in Lisbon. Got a certificate on C level.
For all this I think I would be able to complete your projects successfully and on time.
Best,
Luís
