I am fond of Data Science for 2 years and can say that it is my hobby. During this time I worked in retail, internet advertisement and outsourcing company Ciklum. Now I’m studying at Data Science Master program at UCU. I was a winner of several Data Science competitions. In 2016 I held Kyiv Kaggle Training and UCUracy Kaggle training. In 2017 with my college Alex Ruppelt we created Ukrainian Data Science Club and organized DataFest Kyiv 2017. Moreover, I was a mentor in Yandex and MIPT “Machine learning and data analysis.” courses on Coursera, article author in ODS open ml course.
