We need to design a complex and complete scraping system (HW+SW+configuration) for daily web scraping. The aim of the system is to collect the complete product list (product name, product URL, product price) in .csv from several big ecommerce site on a daily basis. - it's mandatory to use the software SCRAPY ([login to view URL]) and the deamon (scrapyd) so the ideal candidate is a person/team who's already expert in this software (please send us some reference, no scrapy newbie, please). - We need you to design the complete hardware infrastructure using AWS cloud (or similar) capable of receiving the scraping request and to execute the ecommerce crawling and to save a .csv file locally on the server. You can choose the HW, the OS and the software (open source, please). We'll pay the bill for the cloud rent. - We need the performance to crawl each ecommerce site in less than 20 hours so a parallel architechture is requested. - We need a well documented infrastructure with the possibility to extend this infrastructure - Each scraper script need to be polite and not to hammer the target ecommerce site - Each scraper script must collect the complete product list avoiding duplicate product/URLs - Each scraper script must collect the product informations: product name, product URL, product price - Each scraper script must be well commented The list of ecommerce sites to scrape are: [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] We'll release the first milestone when: - complete architecture design - one completely working scraper Please do not hesitate to ask questions to clarify the job.

Dear Sir, I'm very much delighted to let you know that i did data scraping with PHP-cURL, Node.js, Selenium from many sites. I just scraped the data from web site and then wrote the data in mysql database or excel or csv or xml file. I worked on many similar projects, I have big experience in data mining projects. I have written hundreds of web scrapers which scrape millions of pages each day. I'm ready to fulfill your requirement. I can finish this task in short time, with the best quality. I can assure 100% accuracy. Please give me the opportunity to do the work. With Kind Regards, Debdulal Roy Proshanta

Hello! I'm web scraping expert. I use python scrapy framework and selenium library. My scripts can run on windows or linux, but linux is preferably. I can schedule scripts on server if it is required. I can scrape secured and protected sites (http or https), my crawlers can enter into login form, emulate ajax requests etc. If site block IP i can use proxy or TOR. I can try avoid captha on site in avtomatic or manual mode. I can export data into json, csv (excel), mysql, mongodb. I have a lot of finish projects (yellow pages, webshops and other sites with lists of any items). Time to scrape one site: 1-4 days (depend on the different site).

I have extensive experience in this type of application, in fact I made an application that extracted information from some pages of Marvel and filled an Oracle AWS RDS database hosted in an AWS EC2 instance. I also developed a complete application for mobile devices that extracts information portals car sales (prices, years, etc). If you are interested in my services I can prove my authorship in these projects. I am a Systems Engineer with over 18 years of experience, guarantee you a clean and documented code in the stipulated time. I know the scrappy framework.

@zephercode

The project you are proposing needs to be carefully planned and something key here is the scraping platform you are going to choose, for several reasons, probably the most important: - Development Speed: The least the time, the least the cost. Here I always advise a visual programming environment with a large toolset. - Efficiency: you really need to download documents fast, however, you need to have a strategy because you cannot overload servers. You need a technology that can do multithreaded downloading but with supporting rules to avoid overload. - Maintenance: This one is really important, since you are working with different sites. You need to take into account that a site is likely to change breaking up your parsing logic. In this case I dont recommend you to do any programming, but again use a visual environment that let you write robust expressions that will not only hardly break, but also are easy to identify and correct. - Data Integration: What you want to do with the data after you've extracted it? you need a platform that will allow you to do this. Finally, I am expert web scraper with more than 10 years of experience in web scraping and data integration. I have extracted billion of records from ecommerce websites for product repricing, stock sync, etc. Please contact me on PM so that I can give more details about my offer. Basically consists on an affordable scalable and visual scraping platform and about a few hours of my work to scrap each website.

Hi, I'm expert on Scrapy and I have created many crawlers to crawl sites, categorizing the content and much more. I have also experience in deploying Scrapy (and scrapyd) to cloud platforms. I can build such a system easily and you will be very happy if we work together. I'm new to freelancer.com so I don't have any reviews yet. Please send me a message to discuss more about the project. Thanks in advance, axs203dd
