Is he Leonid Sviridenko? https://www.instagram.com/p/CFJiQXQK-zl/ Did he go to Plushenko Academy?
Nice to hear news of Sviridenko! I looked him up after really liking both his programmes from Russian Nationals (check them out!), but couldn't find much info on him. That surprised me, because he has nice skating skills, interesting choreo and good jumps (e.g. 4Lo). Maybe he's just in need of someone to maximise his potential/improve consistency. Anyhow all I know is he used to train with Mishin, then Oleg Tataurov, so this would mean he has recently moved from SPB to Moscow.
