Good day! I'm Java/Groovy programmer with 8 years of language experience and 5 years of experience in data scraping / crawling. I use a bunch of well-known Java frameworks and my own developments. Authorization / Javascript breakage / captcha breakage / multithreading / cluster crawling / Big Data / big number of proxies isn't a problem at all. Wanna have data in your hands? Hire me! Simple web interface developing with Play Framework or Grails and deploy on my/your server or cloud is possible(but I'm not a PRO in HTML/webdesign at all). Desktop applications are also possible. You can hire me through ODesk or directly. Rate is $15-25 per hour, depending on task size and difficulty.
