BIDCAR.EU: Car auctions agregator

Aggregator of car auctions in real time.
I am developing his back-end.
Behind the external simplicity of the site is a complex backend with unique algorithms for parsing large amounts of data in real time, prediction and machine learning algorithms.
bidcar.eu allows you to synchronize real-time prices, bids and data on hundreds of cars from many auctions at the same time, place bids on different sites, and so on. A complete copying of an auction with all photos from the auction site on Bidcar.eu takes a few minutes, sometimes even less.
