From the Founder

Why I Built This

Learning DSA could be the hardest thing you will ever do in your tech career.

I made this platform to relieve some of that pain.

😰

The Problem

When you go to platforms where there are way too many problems and you don't know where to even start, I hear you.

The Solution

This platform exists so you know where to start.

👨‍💻

My Commitment to You

I am a solo developer working on this project, writing tutorials, blogs, making videos so you can understand how algorithms work, how to solve a hard problem in an interview and get the confidence you need to say:

"I can do DSA"

— Saran, Founder of Codstak
