Udemy Abdul Bari May 2026

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.

In the sprawling, noisy marketplace of Udemy—where millions compete for attention with flashy thumbnails, overproduced trailers, and dubious promises of "become an expert in 30 days"—one man has achieved a cult-like status using almost no visual effects, no corporate hype, and a broken marker pen. udemy abdul bari

His name is Abdul Bari.

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." His name is Abdul Bari

His flagship Udemy course, "Mastering Data Structures & Algorithms using C and C++," remains one of the highest-rated and best-selling technical courses on the platform years after its release. Why does Bari work when so many others fail? 10% completion rate).

When Udemy released its "Best of 2023" lists, Bari’s courses were consistently in the top 0.1% for learner completion rates—a metric the industry struggles with (most online courses have a <10% completion rate). People finish his courses.

Essential for CS students and FAANG aspirants. The gold standard for algorithmic thinking. (Just be ready to learn C++ syntax along the way.)
