I have experience in taking care of international customers (in English) and currently working in a cultural exchange organization with students in exchange.
I've also worked in a translation agency in the sales area, contacting direct clients abroad in order to get new direct-jobs into the company.
I am working now as a QAer for the HealthCare campaing. Formating and checking the quality of the texts before they are given final to the client.
My experience with the language is the everyday using of it, writing reports to different agents abroad and some local translations.
