Over two months, Beomhoon Baek enhanced the havuruta/2025-Feb-PS, havuruta/2025-CS-OS, and havuruta/2025-CS-Network repositories by developing algorithmic solutions, refactoring codebases, and expanding educational content. He implemented Java-based solutions for algorithmic challenges, including a depth-first search approach to the Traveling Salesperson Problem, and improved repository structure and documentation for maintainability. In the OS and Network repositories, he curated and updated curriculum materials, adding new questions and explanations on CPU architecture, memory, HTTP protocols, and web security. His work demonstrated depth in Java, Markdown, and technical writing, resulting in clearer, more robust resources for learners and contributors.

March 2025 performance summary: Delivered cross-repo curriculum updates across Network, PS, and OS repositories, focusing on delivering business-value learning materials, addressing gaps, and improving exam readiness. Key features delivered include consolidated Network Chapter 04 README updates with new network concept questions; replaced placeholders with concrete questions; improved readability; and removal of outdated content across 04-1 to 04-3. Chapter 05 added content focusing on HTTP methods (PUT vs PATCH), status codes, and cookie security attributes to reinforce web development concepts. Chapter 07 updated with multiple-choice questions and analyses on load balancing, certificates, and radio wave concepts. In the PS repository, implemented a DFS-based Traveling Salesperson Problem solver to compute the minimum-cost tour visiting all cities exactly once and returning to the start. OS repository improvements include Chapter 05 CPU study materials enhancements with new Q&A on CPU performance, pipeline hazards, and ISA choices; Chapter 06 RAM/addresses/cache practice problems; and Chapter 07 flash memory and RAID learning materials for deeper data-management topics. Major fixes and QA: multiple submission commits to ensure accuracy and readability; cleanup and fixes across network chapters (including W4/W5/W6 related updates) and across OS materials. Overall impact: clearer, up-to-date course content across three domains, improved learner readiness and exam preparation, and scalable content maintenance for ongoing curriculum. Technologies/skills demonstrated: content design and curation, cross-repo version control discipline, algorithmic problem solving (DFS for TSP), networking and web security concepts, CPU architecture, memory hierarchy, and storage topics.
