SDE-3 @ Flipkart, ex-Amazon. Teaching Data Structure & Algorithms(DSA), System design, and Computer Programming for 5 years. Leetcode top 6%. Always available to help you upskill yourself

Helped me understand various concepts on DSA and system design in a very short period of time. I was able to pass interviews and get an offer! Thanks Radib for all your help!

Radib Kar is a highly reliable DSA and System Design teacher with real-world experience at companies like Amazon and TALA. He explains complex topics clearly, focuses on interview prep, and tailors sessions to your level. A solid choice if you're serious about improving.

Radib sir is very good at teaching, he patiently tries to answer whatever doubts that comes to my mind, in the small time I learned from him it was more than what I could in last few years. He also talked about real life experiences and what is important and what I should prioritise in learning as computer programming boundaries are not small. It was a nice time learning from him .

I've really enjoyed learning from him. He has a great way of breaking down complex concepts into simple, easy-to-understand ideas. His sessions are well-structured, and he always makes sure the content is tailored so it's clear and makes sense to everyone. You can tell he genuinely wants his students to understand, not just memorize.

He has an really interesting way of explaining concepts of programming, making them feel like intutions instead of memorizing stuff.

Radib is an exceptional teacher who is not only knowledgeable but also incredibly patient and supportive. His teaching style makes complex concepts easy to understand. His ability to explain difficult topics with clarity and real-life examples makes learning both engaging and effective. I highly recommend Radib sir to anyone looking for a trustworthy and skilled teacher!

In my experience with Radib Sir, I found him very knowledgeable, hands-on and having passion for teaching. He is systematic, and methodical in his teaching approach in Java and related technologies.
He explained the concepts with some real examples. He motivated me to write the code with best practices, and debug it independently, to build confidence in me. He is a thorough professional, who planned the schedule and lessons according to my need. I thoroughly enjoyed learning from Radib Sir, and come a long way in Java and related technologies. Thank you Radib Sir for all your help. Truly appreciate it!!!

It was a pleasure finding Radib, I am very grateful for his help in understanding the system design of an industry relevant project and also in creating my resume. I am entirely satisfied with his mentorship.

Recently, I enrolled in HLD and LLD classes with him. I find it very valuable. He teaches from very basic to very advanced, so that the concepts are easy to grasp.

I would absolutely recommend Radib for DSA classes. He is one of the best teachers I have had for DSA. He explains the concepts very clearly, all the way from basics and has kept me accountable in solving leetcode questions daily. He has been consistently available and very supportive with any doubts and bottlenecks I have.
