Application should be multi-threaded, low memory thumb print. 6. Code should be organised in proper classes, and I should be able to modify the messages that appear etc. 7. Errors should be handled well Description of requirements/functionality: Complete details of what has to be scraped will be provided upon initial contact. Preferred Technologies: .NET Python, PHP and/or a Java application developers welcome. Eventually the script should export records to csv.
