I have developed applications to scrape websites including amazon.com, ebay.com, walmart.com, craigslist.org, gumtree.com and many more websites with higher complexities. I mostly code in Python Scrapy since its specially developed for scraping. But I also code in Python BeautifulSoup4 and Selenium. Moreover, there are several projects which I did in PHP Goutte, a Symfony Crawler. I can store data in any of following: - - MySQL - PostGres - MongoDB - Google Spreadsheets - CSV/Excel
