    I am a freelance web scraper and software developer based in the UK. Over the last 5 years I have scraped hundreds of websites using a variety of languages and tools, including Perl, Python, SQL, and MongoDB. My core expertise lies in writing bespoke software solutions to extract hard to reach data, for example real-time data, encrypted pdf files, websites hosted on Tor, websites using scraping blocking services or other bot detection. I also run standard web scraping services for more common data types such as business price listings, sports results data, and other well structured data. I write my own custom code in Perl and Python, and follow solid software design methodologies and principles to ensure code reliability and robustness. I also am skilled in Matlab, OOP, Linux administration and database management and have completed many one off projects to help clients. I would be interested in hearing from you if you have any relevant projects. ( 03/2014: To all current clients and those who I have been in communication with but not yet started a contract - my hourly rate is the same as it was before. The new rate shown on my profile is for prospective new clients only. )  less

    With many years of experience in various IT companies I am ready to propose following services on "as-needed" basis (sorry, no fulltime employment): 1) Complex engineering tasks related to server-side linux scripts, such as troubleshooting, code review, implementation/adjustment of complicated logic. Supported languages: python, perl, ruby, bash, lua. Haskell, erlang, clojure are possible as well. They are subject of special (lower) rates, due to lack of practical experience (versus solid theoretical understanding and general interest). 2) Advisory in organisational questions for small & medium teams. Workflows, infrastructure, staffing, project management (including risks management, resources management, planning etc). 3) High-level design of the service-oriented architectures, data processing (ETL) flows, devops solutions in linux/cloud environments. 4) Any kind of engineering/architectural work related to functional programming, evented programming, nosql. 5) Advisory/troubleshooting on nginx and hadoop, with basic practical experience in high-load web services and massive data processing. Rates are flexible, depending on particular case. Is this expertise exactly fitting your problem? If so, just message me. Not sure? Message me anyway so we will find an answer together.  less
