    United States - Tests: 6 - Portfolio: 1

    Hi, I'm a back-end developer that specializes in: Python PHP Node.JS On Upwork, I do a lot of scraping jobs because they are usually in high-demand, and I am very very good at taming the DOM. If you're looking at my profile because I applied for a scraping job of yours, please inquire about my previous jobs. Depending on your needs, I can simply emulate a web browser (Mechanize/Selenium), download the raw HTML and tame the output (Requests/BeautifulSoup), or I can reverse the HTTP traffic if you need to automate data input and need faster speed.
