Yet, his fans argue that the "boring" production is a feature, not a bug. It forces focus.
Why? Because by the end, you aren't memorizing algorithms. You are deriving them.
Unlike many online "gurus" with fabricated backstories, Bari’s credentials are refreshingly grounded. An educator and software engineer with a master’s degree from the Indian Institute of Technology (IIT) Kharagpur, Bari spent years in the corporate trenches before pivoting to teaching. He is the founder of the YouTube channel "Abdul Bari" (later extended to Udemy), where his lectures on algorithms began quietly going viral—not because of SEO tricks, but because desperate students would share the links on Reddit and Stack Overflow with the same urgent message: "Watch this. You will finally understand." udemy abdul bari
To the uninitiated, scrolling through Udemy’s data structures and algorithms (DSA) section looks like a chaotic mall. But to hundreds of thousands of computer science students and software engineers, one face stands out: a calm, bearded man in a collared shirt, standing in front of a whiteboard, painstakingly drawing recursion trees.
His name is Abdul Bari.
He picks up a marker (usually green or red) and begins.
However, it is important to note that his course is not without challenges for absolute beginners. Because the course uses C++ as the medium, students without a prior understanding of pointers and memory management may find the initial learning curve steep. Yet, this is also part of the course's value; by demanding a certain level of discipline, it filters and trains students to be more detail-oriented engineers.

One student review on Udemy sums it up: "He doesn't teach syntax. He teaches thinking. After his course, LeetCode medium problems feel like dictation."
Abdul Bari isn’t just an instructor. He is the rite of passage for cracking the coding interview. Because by the end, you aren't memorizing algorithms
