Worked on documentation and content development for the krafton-jungle/KJ-DS-BOOK-9-303 and krafton-jungle/KJ-ALGO-BOOK-9-303 repositories, focusing on building a scalable structure for technical knowledge books. Improved graph documentation by introducing a new Markdown document, restructuring content, standardizing formatting, and reorganizing image assets to enhance maintainability and user guidance. Drafted the second chapter of a number theory book, covering divisors, multiples, GCD, LCM, and the Euclidean algorithm. Emphasized technical writing, data structures, and number theory concepts, while establishing consistent documentation practices to support future content expansion and facilitate easier onboarding for contributors working in Markdown.
