Why? Because by the end, you aren't memorizing algorithms. You are deriving them. His name is 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. Because by the end, you aren't memorizing algorithms

Abdul Bari isn’t just an instructor. He is the rite of passage for cracking the coding interview. 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."

The answer lies in his almost radical minimalism. While modern EdTech favors distracting animations, talking avatars, and slick CGI diagrams, Bari’s video frame is static. You see his face in a small thumbnail; the rest is a digital whiteboard.
