Make parser of goods with AliExpress

You need to make a parser of goods with AliExpress with the ability to display a schedule of changes in value and add coupons to each product. Coupons should also be scraped from several other sites and should not be repeated. Each coupon must be checked for suitability when added and then every day (except for coupons that have a number limit - they are only checked on the first day). The server and proxy will be provided if necessary. Time limits of 2 weeks. In addition to the software part, you need to design the user part in a laconic style in blue and green colors. The logo for the service has already been drawn.
