Dohun established the foundational project structure for the MAMOKEY-25/Github_Mini_Practice repository, focusing on scalable team collaboration and future feature development. He organized the codebase by creating dedicated directories for multiple teams and consolidated ignore rules by introducing a centralized .gitignore file, removing redundancies to streamline repository hygiene. Using Git for version control and shell scripting for file management, Dohun maintained a clean, incremental commit history to support traceability and auditability. While the work did not involve feature implementation or bug fixes, it provided a well-organized scaffolding that enables efficient team workflows and sets clear conventions for ongoing development.
