Hello! As promised, today we are ready to answer questions about the backend in Avito, the development of the server side as a whole and about high loads in particular. How does it work with a site that almost a quarter of Russia's population visits every month? Ask us! We will answer from 12 to 19 hours Moscow time. Under the cut, I represent six of my colleagues who will be in touch with you today and remind you of possible topics for dialogue.
