    Tom S. Agency Contractor

    Mathematician, Programmer and Translator

    Germany - Tests: 18 - Portfolio: 5

    I just finished my studies of mathematics with focus on physics and computer sciences in Iceland. Next to my studies, I have been programming already for several years on a freelance basis and provide professional translation services. The programs that I created so far mostly are GUI applications under Windows, as well as web-based applications using PHP and javascript. In addition to these experiences, I have also intensive knowledge of C/C++, Matlab, R, and various other programming languages. You can see some of my programs in my portfolio and on my website. In addition to being a programmer, I have also several years of experience as a translator. As a German native speaker, I mostly translate from English to German, and occasionally from German to English. I have lived abroad for more than three years now, and therefore know a couple of other languages as well. These include French, Icelandic, Swedish, Dutch and Bulgarian. If you have any further questions, please don't hesitate to contact me. Best wishes, Tom Schiller
