Over a three-month period, contributed to the DaleStudy/leetcode-study repository by building a reusable library of algorithmic utilities focused on core data structures and problem-solving patterns. Developed features such as data analysis tools for duplicate detection and top-k frequency, as well as solutions for problems like Two Sum, ThreeSum, and reverse linked lists, using Python and JavaScript. Applied algorithm design and optimization techniques, including sorting and two-pointer strategies, to improve performance and code clarity. Addressed a key bug in stock profit calculation, enhancing reliability. Emphasized modular code organization and disciplined version control to support ongoing study and rapid solution iteration.
