About Me

I am Vignesh, born and brought up in Tamil Nadu, India.

I did Bachelors in Computer Science in the years 2010 -2014 from Velammal Engineering College. I worked for a leading MNC  for some years and in that process, I discovered my passion to teach students. So I resigned my job without having any backup in mind and started teaching students. From the very first month I launched my online course, I never turned back. It has been an unbelievable jouney sofar, training students in the field which I have been living with for the past 10 years. I always enjoyed Computer Science right from high school till today.

Most of my previous students think me as "genius" after attending my 50 hours courses. But the hard fact is I am a very slow learner. I am no where close to be called as genius. But I am a hardworker. I never get satisfied until I get the concepts and the reason behind these concepts. Having taken the hardest path possible to learn the concepts only through my hardwork, I believe I can explain the concepts in the simplest way possible so that even a slow learner like me will be able to understand it. Don't believe me ? I have trained over 20,000+ students in the past year across 125 countries and more than 95% of my students are very happy with my courses. I get appreciation messages everyday from students that they have used my courses to crack interviews, get good marks,get good jobs,etc. And many students of mine got themselves placed in top notch companies like Google, Microsoft,Adobe and they have used my course extensively in their preparation. This gives me immense satisfaction and force me to work even harder. 

I don’t have a traditional background in CS. Your course helped me get a general overview of what’s happening under the hood. I took a lot of notes from your course. Also, you explained it in such a way that was not intimidating. You have a very relaxed demeanor when you teach, which allows me to relax, too. I was actually soaking in everything! The first few videos introduced turn-around time, etc. along with the CPU, RAM, and Hard Drive and how they relate to each other. I think this was a good start for people who did not completely understand this, like myself. Excellent course! I will be looking out for more!

It was taught really well, sir. I tried various different OS courses before, on Youtube and several other platforms, but couldn’t find a good one, which I could understand properly, as I didnt had any earlier experience with that topic. But then I tried your course and I absolutely enjoyed it as it was taught from very basics and in detailed manner.  I dont know what would I have done in exam, if I didnt came across your course, sir.

I took Operating systems course by tutor vignesh. I really liked his way of explaining the things, all concepts so hard made all clear. Even after months of taking his course I still remember those. All because of the example and questions solved during lectures. Anybody thinking to have a good hold on OS for placements or for academia highly recommended.I am preparing for my job interviews. Taking these courses was very helpful.I am also planning to invest in database courses.

Vignesh is a great teacher, I bought his theory of computation course seeking for help with my studies and I can definitely say I found it! With clear language, relevant resources and smooth development from topic to topic he showed real professionalism and dedication to his work. Additionally, he was always available to answer questions to the fullest and provide more reading materials where needed. I would recommend him to anyone looking to gain computer science skills efficiently and effectively.

Vignesh has an in-depth understanding of the subject matter and explains everything in an easy and comprehensive way. He is approachable and addresses queries until the resolution has been reached. I have learned a lot from his courses and I want to take his future courses as well. He will be a great asset to the project he aligns too. Thank you Vignesh.

I’m going to persue masters and for that i have pre-requisites to complete, among them one is operating systems. And i thought i should complete it before joining so that when my semester starts I will get rid of this OS course by simply giving the exam. I started reading some books but wasn’t that much helpful. Though books are great resources for studies but human intersection also plays a vital role. So i stated OS course provided by Vignesh, and after completion of that i have pretty good understanding on OS. Really Vignesh sir is a great tutor. I appreciated most of the times. Good to learn. One thing I most like of him is that he repeats most of the concepts every time so that we don’t need to go back and have a glimpse of that.

Helped me by explaining all the basics and how it actually work behind the scene in a very simple and perfect way.. it is pretty good for enhancing the knowledge especially for us cs graduates who forgot most of the knowledge and basics, and correcting some terminology we actually misunderstood..

Noora Abdullah

The instructor’s peculiarity is the ability to explain complex topics in simple and clear way, repeatedly returning to the already completed material and repeating the main aspects. The instructor’s aim is not to load you with a bunch of new information, he very intuitively dwells on complex topics and sometimes even explains in too much detail. In the case of operating systems, this technique is absolutely justified!

Andrii Loburets

Hello Sir,I came to know you while doing one of your courses on Operating Systems.It is good!Being from a background of electrical engineering but interested in pursuing CS, I believe that I have being grasping the theory in a right way


Data Analyst, EY GDS, Delhi, India

Was so good, actually i had some classes in the university so i want a good way to remind some concepts and you give all what i want. It is complete course which presents all the basic and relevant topics about operative systems. Also, the exercises done are so clear because are explained step by step. Particularly, I like that everything is explained no matter how simple it is which help to understand more easily

I had taken Database Management System Courses with Vignesh in preparation for one of my courses. I liked that he simplified complex parts and was very detailed in his explanations for better understanding. This course would help beginners and also experts. I most certainly would recommend this course to anyone who would like to go deep into Database management from scratch to expert level.

Jennifer Ibimina (Peterside) Daniel Onwuchekwa

Hi Vignesh, Your Lectures on Operating system are very very Interesting as you have explained all the concepts very Clearly. I read Books like Gavin on operating systems but they are verbose due to which i couldn’t focus & understand what exactly is explained in the book. And more thing i want to say about Threads Concept, which you have explained very well. Thank you very much for your lectures & looking forward for more lectures on Data Structures,Algorithms, networking, C, C++

Great Match for me since I want to understand operating systems thoroughly.This course continues to be thorough.The white board explanations are awesome and the teacher brings clarity to the student.I really appreciate the effort that has been placed in presenting this course.Thanks to the teacher @Vignesh

Raj Kumar Sukhdeo

The lectures are very good. I started with SQL and the concepts to me were not very clear. But this is a solid foundation course for people starting in SQL. I am pretty sure that I would understand SQL better after taking this course. I applaud the teacher for presenting the content in a very simple manner. I hope to see a SQL course soon.
