I'm a math researcher in the Institute of mathematics in Kiev (I've obtained a Ph.D. in probability and mathematical statistics in 2012). Besides the theoretical research, I've been constantly applying gained skills and knowledge in applications. Experienced in working with mathematical models that arise in statistics, financial mathematics, data mining, game theory, algorithms and so on. Also, since 2011 I'm practicing teaching and tutoring (online and remote) in various branches of mathematics (analysis, algebra, probability, operations research, financial mathematics, so on). Skilled in fast problem solving, with clear explanations.
