Professional Translation



“Every project is a new

As a translator, editor and proofreader, I am passionate about my work.

I hold a double degree in English Studies and Translation and Interpreting and am continuously dedicated to pursuing further training in this field. I am currently studying a Master’s programme in Institutional Translation.

Officially qualified as a Sworn English Translator-Interpreter since 1999, my specialty fields include law, marketing and business, human resources, commerce, education, tourism, health, nutrition and social issues.

Institutional Translation in various areas including cooperation and development, inequality, international policies and relations, environment and children’s rights is the main source of motivation in my work and professional practice.
