I am Alexander. I am an admin of Russian Wikivoyage and a liaison between the Russian and English communities. Technically, I am also an admin here, but due to the lack of time and interest I won't contribute here actively beyond inter-language coordination and technical maintenance work.
This website uses the Wikivoyage API to get and display all the information you see. This is the MediaWiki API, which is a general API for accessing data from Wikimedia projects. You can find information about it here: MediaWiki API.
