Moving a python web parsing function to Scrapy

Dear freelancers, I have a simple python program that can parse and extract data from one website and store the data into mongoDB and send an email to notify. The source code is quite simple (core functions are just about 150 lines of code) and is based on python requests. It only extracts certain data from fixed pages/links and will not follow, so it is a not a web-crawler. I have attached two of the core functions, as you can see, they are very simple. And it is single threaded. It works quite well and stable but is a bit slow. As I need to monitor more pages, so I am planning to move it to Scrapy to speed up the program. You don’t need to change the functions of web parsing, database or sending email. The focus is just to use the existing functions in Scrapy to improve the speed and performance. If you need more information, please feel free to contact me. Thank you for your attention.

Dear Sir or Madam, I am a professional ETL Developer maintaining scrapers for several real estates websites for Poland-Based startup mining 45.000 records daily, uploading and updating our databases with deduplication of advertisements. I'm using ScrapingHub with Scrapy with automatic scraping of proxies preventing websites to block input data. Data may be put into MongoDB or stored somewhere else. We maintain our customised docker images. I'd be happy to help model the records. The time provided is maximum time covering testing and documentation. With regards, Michal

Hello! I've just seen you python code and project description. These 2 functions are just part of the workwflow of your one-threaded app. By my opinion it is not the best choice to simply import them into Scrapy, because Scrapy is built on asynchronous Twisted framework and it is working in a bit other way. I can propose you to make a Scrapy spider just using your main logic -- extract required data from strict list of urls. If you can provide me some sample urls and list of data fields you require - I could make you a sample Scrapy spider to make this task. I could provide you with the source code and documentation how to run it and adjusting its settings, if needed.
