Over six months, Joo Kangsan developed and maintained modular algorithm and data structure libraries in the forStudyingJavaScript/leetcode-study and codingTestStd/CoteAndAlgorithm repositories. He delivered reusable JavaScript solutions for LeetCode-style problems, implemented core utilities for arrays, strings, sets, and trees, and expanded coverage to graph algorithms and backtracking toolkits. His approach emphasized maintainable code organization, onboarding documentation in Markdown, and automated CI/CD workflows using GitHub Actions. By focusing on clear technical writing and modular file structures, Joo enabled scalable collaboration and efficient onboarding. The work demonstrated depth in algorithm design, problem solving, and repository hygiene, supporting both learning and production reuse.
