Online Programming Training Platform

Tech Stack

Background

A single platform for problem management, code submissions, online judging, and AI-assisted Q&A, designed to make programming practice more efficient.

Highlights

• Extensible judging for multiple programming languages
• Isolated code execution in Docker
• Microservices architecture with LLM-powered Q&A

Key Contributions

• -Built a microservices architecture with Spring Cloud Alibaba, separating user, problem, judging, and intelligent Q&A services.
• -Used Nacos for service registration and discovery to support reliable calls between services.
• -Designed the online judging module and a Docker-based execution sandbox to isolate submitted code, evaluate results, and record execution details.
• -Applied the strategy and factory patterns to separate language-specific judging logic and execution environments, making the system easier to extend.
