I specialize in data crawling, scraping, parsing and data import to CSV, XML or SQL databases (custom databases or shops like Magento, Prestashop, Opencart etc.). 10+ years of freelancing. I'm ready to provide scalable crawlers and multi-thread scrapers. I developed my own data scraping PHP engine which supports multithread, custom headers, proxies etc. I developed several vertical search engines (Jobs, Real Estate areas) which collects information from multiple sources (websites) to common database. Developed Google Maps API tools such as server-side markers clustering (PHP based solution). Have experience with Amazon and Windows Azure clouds crawlers development. Have a lot of experience in financial data extraction. Also specialize in various backend scripts (shell scripts, PHP or Perl).
