Hi there! I'm working with crawlers past few years and I've done many scrappers including such as e-commerce scrapper, books scrapper, torrent scrapper from websites which requires to be logged in to see content (also .torrent contents grabber and converter) and many more. Last year I did price comparison system for biggest my country e-commerce platforms with auto update function - it was for student university ending (don't know how to call it :/ I hope you will get that) and it was graded 96%. So, I can admit, that I have enough skills to make your vision possible.
