Developed a comprehensive algorithm utilities library for the DaleStudy/leetcode-study repository, delivering 27 new features over five months with a focus on clean, maintainable code. Leveraged Python, C++, and JavaScript to implement solutions spanning data structures, dynamic programming, graph theory, and string manipulation. Emphasized reusable solver patterns, explicit time-complexity documentation, and modular design to accelerate onboarding and future enhancements. Addressed a wide range of LeetCode-style problems, including binary trees, linked lists, and graph traversal, while maintaining consistent coding standards. The work improved codebase coverage, interview readiness, and reliability, establishing a scalable foundation for ongoing algorithmic practice and feature expansion.
