Our Students Speak :



The teacher has fantastic ability to transfer understanding of a concept not just pass along his knowledge of the concept.-Liam Bailes


Great course. Lecturer is full of in depth knowledge and able to pass it on. Its not easy to find this out there. Thank you.

Mark Corrigan


So far, I am finding this course really helpful, and the trainer is really sorted about what he needs to teach and is completely prepared with his plan and material. I feel this is one of the best courses available in Udemy and outside to learn DSA because it is well structured and is delivering what we are looking for.

Ankur Saxena


wlnderful teaching.. completely able to understand the concept in one go..

Shaik Asrar


Well structured classes, and I was able to assimilate the concepts with ease.

Elisha Benjamin


Thanks Sir! For making such a great course. This course help me out to learn basics of DSA. The way of your explanation is great. Once again Thank you so much Sir!!!



Makes us understand DSA concepts very easily



Because of this course I understand how to find complexity of the program. Teacher has explained concept in very easy manners, so that any body can understand it properly.

Amritesh Kumar Singh


Just what I needed for my university studies. I had struggles with the Big O notation but he explained it pretty well. Thanks!

Aaron Engelmann


This course is excellent and a great method to learn about Data Structures and Algorithms. It’s fantastic for learning how to solve problems and construct reasoning.-Parth


Best course. Since Data structure is one of the basic subject for programming, this course provides an complete overview of all components of Data Structures. This course is very good for students at the beginner level who wants to know the fundamentals and advanced concepts of Data Structures and Algorithms.-Newton


The course is really helpful, Must learn course while preparing for Tier 1 companies. Explains the concepts well and in an easily understandable way.-Dennis Paul

Welcome to the Coding Interview Bootcamp – (Python and Javascript) !

Once you get an interview from a top tech company, the only thing that matters for you to get your dream Software Engineering role is your performance in the coding Interviews.

The only way to ace the coding interview is to take one problem at a time and really understand how to solve it and then do this for a lot of problems to get sufficient tools and techniques in your arsenal to face and conquer any coding interview. This is what my aim is for you with this course.

This course is structured as DAILY CODING CHALLENGES to give you a clear target for every day. By not missing a single day and by staying consistent you will have solved a variety of questions by the end of this course, getting you prepared for coding interviews and more practice on your own from Leetcode.

We start right from the basics and discuss Big O analysis and then move on to cover the common data structures and then discuss real life problems asked in Big Tech companies such as Google, Meta, Amazon, Netflix, Apple, Microsoft etc.

For Each Question we discuss :

   1. The Logic or the method by which we can approach this question in an optimal manner

   2. The Time and Space complexity of the Solution

   3. Code the Solution in Javascript ( You can follow along in any coding language of your choice)

This course also includes multiple downloadable resources, trackers to keep you motivated, and cheat sheets to make your coding interview prep smooth.
