During June 2025, S2342106VN developed two core front-end features for the yabukilab/yabuki-b repository, focusing on user authentication and profile management. They built a form-based login page for the Reading Record Exchange App, implementing email and password input handling with CSS and JavaScript to support a seamless authentication flow. Additionally, they overhauled the user profile interface, redesigning the header, enabling editable usernames, and introducing card-based comments and work item ratings using HTML, CSS, and PHP. This work enhanced user onboarding and engagement, laying a solid foundation for future integration and performance improvements without addressing major bug fixes this period.
