About Debug Challenge
Building a community of developers who excel at finding and fixing bugs through deliberate practice and knowledge sharing.
Our Mission
Debug Challenge was born from a simple observation: debugging is one of the most important skills a developer can have, yet it's rarely taught systematically.
Our mission is to help developers of all experience levels become confident, efficient debuggers through daily practice, carefully designed challenges, and educational resources that explain not just how to fix bugs, but how to think about problem-solving.
We believe that with deliberate practice, anyone can develop the debugging intuition that separates great developers from good ones.
We've found that engineers who excel at debugging tend to be 3-5x more productive than those who struggle with it, regardless of their experience level.

Our Values
Bugs as Opportunities
We see bugs not as failures but as opportunities to learn and grow as developers. Every bug teaches something valuable.
Deliberate Practice
We believe in focused, intentional practice that challenges you at the edge of your abilities to build true expertise.
Community Learning
The best learning happens when developers share insights, approaches, and mental models with each other.
Meet the Creator
Dejan Stajic
Founder & Developer
Created Debug Challenge to help developers improve their debugging skills through practical exercises. Passionate about building tools that help developers level up their abilities and become more efficient problem-solvers.
Our Story
Debug Challenge started when I noticed that the ability to efficiently debug problems was the biggest predictor of a developer's overall effectiveness—more than years of experience or technical knowledge.
After searching for resources to help improve debugging skills and finding mostly scattered blog posts and books that focused on language-specific tactics rather than fundamental debugging mindsets, I decided to create a platform that would systematically help developers level up this critical skill.
The platform launched with daily challenges focused on JavaScript and quickly expanded to support multiple languages. Today, Debug Challenge serves developers around the world who are committed to mastering the art and science of debugging.
