For most of my life I was professional chess player: grandmaster, world No.5 in July, 2009. My two other passions have always been mathematics and programming. In 2017 I decided to gradually quit chess and switch to software engineering. I have succesfully applied to Yandex School of Data Analysis as a student and later to Yandex as a software engineer.I like to face challenges and strive to make real world impact.Some of my best chess achievements can be found here: https://en.wikipedia.org/wiki/Dmitry_JakovenkoNow I work hard to make an equally impressive list on my new career path.
