I built a "Chess Puzzles for Developers" app to help build active coding habits
Hey r/learnprogramming,
I'm a professional software engineer primarily working in Python, but lately, I've been doing a focused study of DSA in C++ to improve my active coding abilities and get a better grasp on memory interactions. During this process, I realized that while grinding long algorithms is incredibly useful, I was missing a way to drill quick, rapid-fire syntax and logic exercises—something akin to doing tactics in chess.
So, I built CodeQuizz (codequizz.com).
The core idea is simple: it generates short, focused coding puzzles to train your execution instincts.
Here is how it works:
- Infinite AI Puzzles: Instead of static questions, an AI engine crafts clean, production-grade code snippets with bugs, missing return types, or logic gaps for you to identify. Because they are generated dynamically, every run is unique.
- Tactics Elo: It tracks your performance with a dynamic rating system (just like chess), so you can actually watch your engineering logic improve over time.
- 36 Languages Supported: Whether you are working in Python, diving deep into C/C++, or exploring something else, the environments are ready.
It's currently in Public Beta, which means it is completely free with unlimited access.
I’d love to get some feedback from this community. Check it out and let me know what you think. I'm actively looking to improve the engine!
