    English and French Translator, Editor and Proofreader

    United Kingdom - Last active: 29 days ago - Tests: 5

    I have worked as an editor and proofreader for several companies before, from academic essays (as an example, a study of the work of a French philosopher), fictions and biographic novels (a travelogue from Europe to Asia), a funding application for a project between Bolivia and Belgium (I was not in charge of the Spanish part of the project, but the editing of the French and the translation of the English applications), webpages and PowerPoint presentations for several companies. For several of these jobs and positions, I have acted as an editor but also a translator when necessary. As a French and English native (thanks to my international education), I am perfectly bilingual in both languages. On top of that I have two Masters' degrees, one from the University of Paris (Sorbonne) and one from the University of Cambridge (UK). My perfect knowledge of these two languages allows me to produce very accurate translations, as I understand all the nuances in French as well as in English.
