Over a three-month period, contributed to the SSAFYnity/Job-Preparation-Challenge repositories by developing 40 algorithmic features focused on grid, graph, and dynamic programming problems. Leveraging Python, implemented solutions such as LRU cache simulations, BFS-based pathfinding, and scheduling optimizers, each designed for performance and edge-case resilience. Applied advanced techniques including disjoint set union, sliding window, and heap-based scheduling to address real-world scenarios like resource allocation, coverage optimization, and data validation. Emphasized correctness and scalability through robust testing and efficient data structures, delivering features that improved lookup responsiveness, operational efficiency, and decision support across diverse problem-solving domains without introducing regressions.
