Contributed to the TeamSparta-Inc/sparta-algorithm-study repository by developing six algorithmic features over two months, focusing on memory-efficient solutions and onboarding improvements. Implemented in-place array merging and alternate string merge utilities using JavaScript and Swift, emphasizing direct data manipulation and runtime efficiency. Enhanced project documentation by introducing comprehensive READMEs for LeetHub, streamlining contributor onboarding and clarifying usage. Delivered additional utilities such as a highest altitude calculator and a flowerbed planting feasibility checker, each accompanied by lightweight performance profiling. The work demonstrated a methodical approach to algorithm design, maintainability, and documentation, supporting both code reuse and measurable performance benchmarks.
