Jul 1, 2025July 2025: Delivered a cross-language algorithm problem-solving suite in hanaro-algorithm/algorithm, expanding SQL data queries and multi-language solutions (JavaScript, Java). Implemented five weekly problem sets (55–58주차) covering BFS/graphs, greedy optimization, MinHeap scheduling, DSU, DP, and ASCII decoding, with reusable scaffolding for future exercises. No explicit bug fixes recorded in this month; primary business value is a scalable reference platform that accelerates problem-solving readiness, onboarding, and code quality. Key technologies demonstrated include SQL, JavaScript, and Java with data structures and algorithms (graphs, DSU, DP), plus code scaffolding and documentation.

Jun 1, 2025June 2025: Delivered the 54th Week Algorithm Challenge Suite for hanaro-algorithm/algorithm, consolidating SQL data retrieval tasks and multi-language solutions (JavaScript/Java) for dynamic programming, BFS, and classic problems. Established a centralized feature set with 54th-week folder scaffolding and complete problem coverage across data queries (purchase history, restaurant info, department salaries, price grouping) and algorithms (DP, BFS, Josephus, Strahler numbers, word learning, team power calculations). This work improves reusability, onboarding, and maintainability, enabling faster replication of challenge solutions across teams and clearer traceability of progress across language implementations.
