    Experienced Webmaster/Web editor/writer/Copywriter/Proofreader/

    Sweden - Last active: 1 day ago - Tests: 6 - Portfolio: 3

    I am French (bilingual italian) and I have been living in Sweden since 2011. I am currently looking for a position corresponding to my experience either as a Writer/ Webmaster/Copywriter/Proofreader or translator /SEO translator (ideally working from home). After an extensive period of training (in Languages, Literature and Multimedia), I have been working for the last 15 years in the Web sector where I held several different positions (webmaster/web editor/writer/proofreader/copywriter). Over the years, I had to face the permanent challenge of adapting my work to ever changing demands from clients while staying as close as possible to the fast-moving requirements of the media sector. This challenge gave me the opportunity to develop and deepen my skills further allowing me to match as closely as possible the ever demanding needs of the sector. Thus, my skills have become over time more technical and graphic-oriented, although the text itself has remained at the core of my work. A genuine sensitivy for literary work - and more generally literature - meant that my professional work has always been guided by a true concern for rigour and conciseness. Finally, I had throughout my life the opportunity to live in different countries and to evolve in various cultural environments. This gave me an ability to adapt quickly to people as well as circumstances and to develop the open-mindedness required in today’s multicultural world.
