Vy Nguyen developed the initial UI/UX design foundation for the SE4CPS/PlantWaterSystem repository, focusing on early-stage prototyping to facilitate rapid frontend iteration. Using paper prototyping techniques and Markdown, Vy established a structured directory and organized visual assets for core screens such as home, login, plant detail, and welcome. This approach provided stakeholders with tangible design references and streamlined the asset pipeline for future frontend integration. The work emphasized prototyping and UI/UX design skills, enabling efficient design reviews and feedback cycles. Over the course of one month, Vy’s contributions laid the groundwork for consistent and maintainable frontend development in the project.
