Algorithm competitions
I participated in ACM ICPC and TopCoder competitions (as griffon) competing and setting problems in TopCoder Open Algorithms Finals.

Teaching algorithms for high-school students
I was teaching advanced classes in algorithms for high-school students for ~5 years, coaching teams for algorithmic competitions. I participated in preparation of training camps and contests for Russian Olympiad in Informatics and International Olympiad in Informatics (both in Russia and in the U.S.).

Non-profit in education for high-school students: Homepage, Group on Vkontakte
In 2009 I co-founded a non-profit organization focused on advanced extracurricular education in algorithms for high-school students (5 – 10 grades) in St. Petersburg, Russia. In 2013 it was expanded to Moscow and Yekaterinburg.
In the early days we were supported by

Triathlon and Duathlon
If I am not working then I am probably practicing for the next
(more pictures). Let's do it together! ;)
In 2017 I was representing Team USA in the M30-34 age group at the ITU Standard Distance Duathlon World Championship in Penticton, Canada. In 2019 I will be representing Team USA in the M30-34 age group at the ITU Long Distance Triathlon World Championship in Pontevedra, Spain.

Software Engineering
In 2007–2008 I was lucky to be a part of the FBReader team. This is an open source free e-Book Reader project.
We developed the first version of FBReader for Android (now > 10M downloads worldwide on Google play).

Very nerdy!
There are some things I can't prove but rather just believe in. E.g. this logo I designed and proposed for the CSTheory website.

Education
St. Petersburg Academic University is a unique center for continuous education in physics and engineering, run by Zhores Alferov, a Nobel Prize winner in Physics. In 8 years there I finished high school, B.S. and M.S. (a pilot class in theoretical computer science where I was the first student). I am forever grateful to all my teachers during those happy years!
Here is a recent video (in Russian) about the new bachelors programs at the Academic University.
