Worked on the dungkhmt/openerp-micro-service repository, delivering twelve features and resolving three bugs over three months. Focus areas included enhancing the code runner’s stability and performance through C/C++ build environment consolidation, resource limit hardening, and Java execution tuning. Integrated Judge0 for automated judging workflows, improved multilingual support, and upgraded UI components using React and Material-UI, such as tag-based data filtering. Maintained CI/CD pipelines with Docker and GitHub Actions, optimizing workflow costs and repository hygiene. Applied backend development skills in Java and JavaScript, emphasizing clean code practices, configuration management, and system reliability to support programming contest and timetabling systems.

Month: 2024-11 — In the dungkhmt/openerp-micro-service repo, delivered two focused improvements and associated hardening to improve stability and performance of the coderunner. 1) C/C++ Build and Execution Environment Enhancements: consolidated the build and execution environment, including rollback stabilization of build commands, reintroduction of performance-oriented optimizations and architecture-specific tweaks to improve reliability and speed in code execution, plus the addition of a compile flag to boost consistency. 2) Resource limit hardening for code execution and compilation: tightened resource constraints to prevent crashes and allocation failures during code execution and compilation (ulimit for C++11, increased file size limits for C/C++/Java). These changes reduce crash risk, improve reliability and predictability, and enable safer user-submitted code execution. Business value includes more stable runtimes, fewer user issues, and easier maintenance. Technologies/skills demonstrated include C/C++ build systems, resource management, performance optimization, and reliability engineering.
