CodeMaster

CodeMaster is a distributed system to support collaborative coding challenges, inspired by coding platforms such as LeetCode. With CodeMaster every user can create, manage and resolve different coding problems, using different languages. 

In fact, its primary goal is to provide an extensible and scalable environment to practice problem solving, evaluate algorithmic solutions, and integrate advanced architectural concepts. 

CodeMaster is designed not only as a learning tool, but also as a practical environment to strengthen and refine individual coding skills through continuous practice and feedback. For this reason, the platform is intended not only for experienced programmers, but also for beginners who are approaching the world of computer science for the first time. 

The system provides services for solution submission, problem management, evaluation, and user interaction. Each service communicates through lightweight APIs and asynchronous messaging, enabling fault isolation, high availability, and independent scalability. This design choice supports distributed deployment and eases the integration of new features without disrupting the overall system. 

From an educational perspective, CodeMaster is not only a coding practice tool but also a case study in modern distributed systems. This demonstrates how principles such as service decoupling, resilience, observability, and scalability can be applied in practice. Furthermore, the project highlights challenges in consistency management, interservice communication, and error handling in distributed environments. By combining practical coding features with advanced architectural design, CodeMaster provides both end users and developers with a robust environment.
