In October 2024, Jin delivered three Java-based optimization utilities in the onestone11/kosa-study-tigger repository, each addressing classic algorithmic challenges. He developed a Coin Change Optimizer that applies a greedy algorithm to minimize coin usage for a target amount, a Gym Clothes Distribution Optimizer that maximizes student participation by prioritizing lending to direct neighbors, and a Largest Number From Digit Removal Tool that constructs the largest possible number by removing specified digits. Jin’s work demonstrated strong skills in algorithm design, array and list manipulation, and string processing, with clear commit traceability and a focus on maintainable, auditable code structure.

October 2024 — Delivered three Java-based optimization utilities in onestone11/kosa-study-tigger that deliver immediate business value: Coin Change Optimizer, Gym Clothes Distribution Optimizer, and Largest Number From Digit Removal Tool. Implemented greedy-based solutions to minimize coin usage, maximize participant reach, and construct the largest number by digit removal, with clear commit traceability to enable fast audits and future enhancements.
