During December 2025, Joon worked on the cpinitiative/usaco-guide repository, delivering four new features focused on cross-language USACO problem solutions and developer experience improvements. Joon implemented the Shell Game and Maximizing Productivity solutions in C++, Java, and Python, ensuring correctness through simulation and input-driven logic. Legacy code was removed and core algorithms were refactored for better readability and performance, notably by replacing arrays with vectors and tightening comparison logic. Documentation was migrated to MDX with improved Markdown formatting, and VSCode settings were updated to streamline onboarding. The work emphasized maintainability, cross-language consistency, and a more efficient development workflow.
