PhD at University of California teaches Propositional Logic, First-Order Logic, and Non-Classical Logics.

From 51 C$ /h

In my classes, I employ a dynamic and engaging teaching approach that combines traditional lectures, thought-provoking exercises, and challenging logical puzzles. I firmly believe that philosophy is not an isolated discipline but rather a vital link between various other sciences and real-world problems. As such, my teaching philosophy revolves around exploring the intricate interplay between philosophy and other scientific disciplines, bridging the gap between theory and practical applications.

This class is designed for high-potential students, from Grade 3 to Grade 12, aiming for the world’s most competitive mathematics competitions — the same competitions that act as strong signals for admission to Ivy League, Oxford, Cambridge, MIT, Stanford, and other top global universities.

I provide elite-level training in mathematical problem-solving, logical depth, and creative reasoning, focusing on competitions that identify exceptional talent rather than routine academic performance.

Major competitions covered include:

- AMC 8 / AMC 10 / AMC 12
- AIME
- IMO pathway (advanced problem-solving foundations)
- European & Asian Olympiads
- National and international math competitions
- SASMO, AMO, Fermat, Kangaroo, Gauss, Euclid competitions and others

Invitation-based and high-prestige contests recognized by top universities

These competitions are not about speed or memorization. They require original thinking, multi-step reasoning, and mathematical maturity — skills that universities actively look for in exceptional applicants.

My approach

I train students to think like mathematicians.

Students learn how to:

deconstruct complex, unfamiliar problems

identify hidden structures and elegant solution paths

apply advanced techniques from algebra, number theory, combinatorics, and geometry

write clear, rigorous, competition-level solutions

remain calm and strategic under high intellectual pressure

This is not school math and not standard tutoring. Sessions are intellectually demanding, highly structured, and tailored to the student’s current level and long-term goals.

Who this class is for

students with strong mathematical ability who want to reach elite level

students targeting top universities (Ivy League, MIT, Oxford, Cambridge etc.)

students preparing for national or international math competitions

families looking for long-term talent development, not short-term fixes

Instructor background

With extensive international experience in advanced mathematics education, university-level teaching, and mentoring high-achieving students, I understand how competition mathematics connects directly to elite university admissions and academic success.

I do not train students to “collect medals.”
I train them to develop exceptional mathematical thinking — the kind that opens doors.

Format

Sessions are highly personalized, challenging, and progressive.
Online via webcam.
Languages of instruction: English, Russian, Turkish, and Azerbaijani

Experienced and patient teacher of logic for computer science.

I have taught logic, formal languages and automata theory to undergraduates for six years. My tutoring is adapted to the student's level and goals. Whether you need to learn logic for your studies, or you would simply like to know more about the subject, I will be more than happy to help you improve your understanding and skills.

Logic
The sciences presuppose a certain standard of rationality. An ability to distinguish between correct reasoning and claims that do not follow from the assumptions. In this class we study the basic principles of logic and apply mathematical techniques to the study thereof.
Topics include:
Propositional and Predicate Logic
Syntax and semantics
Natural deduction
Semantic tableaux
Correctness and soundness
Completeness

Formal languages and automata
A formal language is an abstraction of general characteristics of programming languages. Such a languages consists of a set of symbols together with some rules to determine whether a string made up out of those symbols is a member of the language.

Topics include:
Regular languages, context-free languages
Finite automata, pushdown automata, Turing machines
Regular expressions
Regular grammar, context-sensitive grammar
Pumping lemmas for regular and context-free languages

It is true that the philosopher is the friend of wisdom, but above all, he is someone who does not want to make mistakes in reasoning. Philosophizing is a way of reasoning and a way of solving problems that will never have a perfect and definitive solution. Knowing the distance between the Earth and the Moon is not a problem of philosophy, because it is enough to measure to solve it. On the other hand, knowing, for example, what justice is, is a problem of philosophy. A meter will not be able to help us know the answer. We must go about it differently, and in the courses I offer, I will teach you how.

You will learn

- text reading strategies
- case studies with the aim of learning from experts
- methodology in philosophy
- writing an essay
- writing a text commentary
- a work on the philosophers of your choice
- an overview of the history of philosophy
- the general culture necessary to be able to philosophize

I will adapt to your individual needs. Each course is tailor-made. We will analyze where your difficulties lie and together develop a course program that will make you perform as quickly as possible. The basic principle of the courses I offer is dialectics, like Plato's dialogues: reflecting together, making theoretical contributions, asking questions and seeking answers, and testing the validity of reasoning.

For the past 10 years, I have been teaching German using the philosophy methodology, having studied philosophy at the Master's level at Aix-Marseille University. It turns out that the analytical mind is very useful even outside the confines of philosophy. Today, there are even fields of activity such as management with philosophy or philotherapy. In recent years, some German students have asked me to also teach them philosophy courses, and that is why I decided to offer philosophy courses directly.

I look forward to meeting you during a first lesson.
