Developed a reusable, contest-ready problem-solving library for the cold-weather-coding-test-study/coding-test-certification repository, focusing on core algorithm domains such as graph theory, dynamic programming, and binary search. Delivered end-to-end solutions including Floyd-Warshall all-pairs shortest paths, tree parent discovery, BFS and queue-based traversals, and a range of greedy, backtracking, and brute-force problems. Enhanced code quality and maintainability through targeted codebase cleanup, removal of unnecessary comments, and checkpoint progress saving for Baekjoon problems. Utilized JavaScript and Python to implement robust solutions, broadened contest coverage with new problem assets, and improved onboarding speed by emphasizing reliability and maintainable engineering practices.
