I have 12 years of teaching experience in handling automata and theory of computation, compiler design and decent knowledge in machine learning concepts.

if you are interested to check my subject knowledge first listen my demo class or give some sample questions . i will give 100% perfect answers compared to other teachers

I am currently a Associate Professor in JNTU HYDEARBAD.

I have a lot of in-depth knowledge of different subjects of Computer Science.

I can help the undergraduate students to have excellent grades.

I love to teach in a friendly manner.

I have Excellent knowledge about various topics of the subjects like
1. Finite automata
2. Mealy and Moore machine
3. Regular Expressions
4. Context Free Grammar
5. Push down Automata
6. Turing machine
7. Theory of Automata and compiler Design

I can make students understand the concepts in computational theory and my methodology is to train students to design their own machines from the scratch.

I am very confident in this methodology since I always achieve 100% pass percentage in the above subjects. I also look forward to solve complicated assignments.

The teaching fee is also nominal and I assure the students that my classes will surely help them not only to clear these subjects but also to gain utmost knowledge in these areas.

By keeping the things very simple my students learn very quickly the difficult concepts

I have great sense of humor my students enjoy learning from me.

I am very much sure after learning from me you can easily attempt your papers and get higher grades.

I really care for my students, push them to work hard, and to show their full potential.

each person’s ideas and opinions are valued. Students feel safe to express their feelings and learn to respect and listen to others.

I want my students to be happy while they are with me everyday.”

I try to encourage my students to do their best and never give up on themselves.

I push my students to do their best, even when it is hard for them. At the end of the day, they know that I really care about them

Most importantly to me though, is that I care deeply about each one of my students, and I know in my heart they all know that.

Finally, and simply … I bring out the best in all my students
