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.

Computer Programming

I am a senior computer science major at Columbia University and have an extensive experience with computer programming through my studies as well as outside of school. I have taken many courses on computer programming, including Java, Python, C, and C++. I have also completed many projects of my own in computer programming.

Computer Science

I am a senior computer science major at Columbia. As a computer science major, I have taken classes on various subjects in computer science. For instance, I learned the fundamentals of computer science in my computer science theory class, where we learned in detail about the automata theory. I also completed a class on computer organization and digital circuits.


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 completed a 3 month internship at Change My World Now where I worked on the startup's web application. During my internship, I gained a great amount of knowledge on programming in Javascript, since the application I worked on was written in React JS. I worked side by side with experienced Javascript programmers who helped me improve my existing skills as well as acquire new ones every day I spent at the internship.


I have taken a python class at Columbia, where I am a senior computer science major. I have also written several applications in python outside of class. In particular, I wrote a web application in Python and Flask as a personal project. The application detects what neighborhood the user is located in New York based on their location.


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!
