What is AMA? This format is very popular on Reddit. You tell about yourself and invite readers to ask any questions: Ask Me Anything! The teams of professionals do it especially well - as a result, a series of short and useful thematic conversations are obtained. We like Reddit, the AMA format itself and Habrahabr, so we also enter the game and invite you to the dialogue here. This post is the announcement of the question and answer section, which will run on the Avito blog on October 13, on Friday, from 12 to 19 hours Moscow time. On this day at AMA, five of my colleagues who are engaged in the development of the Avito server part will be in touch with you. And under the cut, I remind you what you can ask them.

So, on Friday we will be in touch and ready to tell you how it works with the site’s backend, which is visited by 35 million people every month - this is a quarter of the Russian population. You can talk on the following topics (but not limited to them):

• device of our internal projects;
• success stories and failures;
• high loads and that's it;
• what we saw in PHP, and why we use Go and Python;
• how our search on Sphinx works;
• and so on.
