About Denis

I am bilingual and offer tutoring in both English and Russian languages. I am currently attending Columbia University where I am Junior Computer Science major. I offer tutoring in various Computer Science related subjects, as well as in writing, biology, and more. For a complete list of subjects, please see my profile.
I enjoy to watch people progress as they learn more about the subject and begin to understand it better. As a rule, students that need tutoring require a strictly individual approach when it comes to explaining the subject. Therefore, I always emphasize that a good tutor has to have tremendous patience as well as use and develop his/her creativity in order to maintain an environment that is most suitable for the student.

Approved subjects

In most cases, tutors gain approval in a subject by passing a proficiency exam. For some subject areas, like music and art, tutors submit written requests to demonstrate their proficiency to potential students. If a tutor is interested but not yet approved in a subject, the subject will appear in non-bold font. Tutors need to be approved in a subject prior to beginning lessons.


I am a junior Computer Science major at Columbia University. I gained my initial knowledge of Java in the Introductory Java class at Columbia; this class was very challenging as well as comprehensive and gave me a good foundation in understanding Java programming language. I have also taken Data Structures in Java, which helped me improve my fluency, solidify my existing knowledge of Java as well as add necessary depth to it.


I am a native Russian speaker fluent in English. Russian was always one of my top favorite subjects when I went to school in Russia and I surely enjoy teaching it to students of all ages! Whether you need to brush up your grammar and conversation skills or if you are a complete beginner, I would love to help you in your journey of mastering this beautiful language!
