Introduction to
Algorithms & Data Structures

Go from “I can code” to understanding why code is fast or slow, acing technical interviews, and writing solutions you trust—not ones you copied.

After this course, you will

Stay ahead in the age of AI

Claude, Cursor, and Copilot make everyone faster—but only strong problem solvers can steer them, catch their mistakes, and build things that actually work.

Pass technical interviews

Solve problems with real understanding, not memorized templates—so you can handle the ones you haven't seen before.

Understand performance

Know why code is fast or slow and how to make it better.

Become a stronger engineer

Build the CS foundation that separates good developers from great ones.

How every lesson works

💡
Concept — each pattern explained visually with animations before any code
🔍
Problem — solve a concrete problem together, tracing through real examples
</>
Code — by the time you see the code, it shouldn't surprise you

About the instructor

I teach algorithms the way I wish someone taught me: visual-first, building real intuition instead of memorizing steps. Every lesson uses animations to make the invisible visible, so you understand why things work—not just how to pass the test.
