About Codetree
Codetree is a coding learning platform built by international programming competition medalists and algorithmic experts.
We cover everything from basic syntax to beginner, intermediate, and advanced data structures and algorithms.
Unlike other platforms that just offer problems, we explain key concepts, guide you step-by-step through a structured curriculum, and our in-house experts answer your questions within 24 hours.
Since launching in the US, Canada, and India in early 2025, we've already helped numerous students land jobs at Big Tech companies like Meta and AWS.

By the end of this Challenge, you'll be saying:
"Take this course, no question about it. You can physically feel your skills improving every day over the three weeks. Most importantly, I finally found joy in solving algorithmic problems. I had never enjoyed coding before, but now that I understand the concepts and can solve problems, I'm thinking 'Hey, maybe coding is actually fun?' Among all my academic activities, this was by far the most beneficial and growth-inducing program.”
