    Mathematician, Programmer and Translator

    Germany - Last active: 2 days ago - 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

    Jonathan Meier Agency Contractor

    Data Scientist/R and Python Developer

    United States - Last active: 5 days ago

    I study Computer Science and Economics in the US. I have been doing statistical data analysis in R and python development for 2+ years now and have experience working with a variety of single/multiple regression and /multivariate time series models, clustering techniques, and survery data. I have also developed a specialty in machine learning techniques, particularly Random Forest, kNN, k-means, C4.5, and CRAN. I specialize in creating meaningful reports and visualizations that allow everyone-even non-statisticians-to understand complex expressions of statistical analysis. Heavy experience using ggplot2 within R. Almost anyone can run a statistical analysis, but it takes skill to craft something that is digestible and easy to understand. I am a dedicated and hard worker, and guarantee a useful product delivered in a timely manner.
