About Karthikeyan
I am an experienced software developer with 15 years of experience in the .NET ecosystem. I am passionate about sharing my knowledge and helping aspiring developers build strong programming fundamentals.
My lessons focus on understanding Data Structures and Algorithms (DSA) through simple explanations, practical coding examples, and step-by-step problem-solving techniques.
Whether you are a beginner learning DSA from scratch or a developer preparing for coding interviews, I aim to make complex concepts easier to understand and apply.
My goal is to help students develop logical thinking, improve coding skills, and gain the confidence to solve programming problems independently.
