During July 2025, Cukibyeol contributed to the chobee81/study3 repository by adding two new binary image assets to support branding and user interface updates. The work focused on asset management within Git, ensuring that the images were properly uploaded and versioned for immediate integration into the UI. No functional code changes were made, as the primary goal was to provision branding resources efficiently and prepare the repository for faster visual refreshes. This approach streamlined future asset updates and reduced turnaround time for UI changes, demonstrating skills in binary asset handling, repository organization, and rapid provisioning of design resources for frontend development.
