    Perl, Python programmer, web scraping / data extraction

    United Kingdom - Last active: 2 days ago - Tests: 5 - Portfolio: 1

    I am a freelance software developer providing web scraping services and data crawling using Python and Perl. Over the last 5 years, I have developed a wide range of software solutions to crawl and extract different types of data from a myriad of websites, e.g. real-time data, business listings, sports results data and other related data sources. My experience lies in automated web scraping with well defined specifications including website and output format. Website data delivered often are in standardised CSV or SQL formats and typically involves further post-processing of crawled data according to your requirements. Code is written in Python and Perl following agile and TDD software design techniques to ensure code longevity, reliability and robustness. I also have experience in mathematical languages Matlab, R, as well as databases SQL, MongoDB, Linux administration, and many web API's including Dropbox, Twitter, Twilio and Sendgrid. As well as web scraping, I am capable of completing similar web related projects using Python and Perl, for example, filtering log files, web monitoring, notification systems and backend web apps. Please contact me if you have any available projects!

    Data Scientist

    Spain - Last active: 1 day ago - Tests: 16 - Portfolio: 5

    Do you have some question that requires a statistical or machine learning answer? No problem. As a data scientist with 15 years of experience, I have the technical knowledge and the communication skills needed to solve your problem and, most important, give an answer that you can apply to your field of interest. What I offer to you is a full data analysis/machine learning stack, including: - Getting and organizing your data. - Selecting the most relevant statistical or machine learning technique for your case. - Applying the technique to your data. - Writing a report that explains every step taken and makes a interpretation of the results. All written with enough technical detail, but that doesn't require a depth statistical knowledge to follow. - Assistance in applying the results to your specific field. I can do all this using any or several of the following: R, MATLAB, Python, MySQL. Everybody can apply an out of the shell statistical algorithm to some benchmark data. But I'm an expert in the tricks needed to apply those algorithms to real data.
