    Perl, Python programmer, web scraping / data extraction

    United Kingdom - Tests: 5 - Portfolio: 1

    I am a freelance software developer providing web scraping and data crawling services using Python and Perl. Over the last 5 years, I have developed code to crawl and extract different types of data from numerous sources including e.g. real-time data, websites requiring authentication, business listings, real-estate, and sports results websites. My expertise lies in automated web scraping given well defined specifications including website urls, keywords, search terms, preferred output format and update frequency. Data output usually is in CSV or SQL format and includes further post-processing of crawled data according to stated requirements. My source code is written in Python and Perl, using version control Git and following agile and TDD software design techniques to ensure code longevity, reliability and robustness. I prefer writing my own code but I also use websites and tools such as Selenium, import.io to further increase my productivity. I have experience in other languages Matlab, R, C++ for statistical analysis as well as databases SQL, MongoDB, and experience in Linux administration and many web API's including Dropbox, Twitter, Twilio and Sendgrid. I am capable of completing similar web related projects using Python and Perl, for example, multi-threaded applications, filtering log files, web monitoring, notification systems and web apps. Please contact me if you have any available projects.
