Andrew worked on the NYCU-Service-Learning/nanao-system repository, focusing on user interface and experience enhancements over a one-month period. He implemented a responsive home screen using CSS and frontend development techniques, ensuring the application adapts smoothly across devices. Andrew also developed an in-screen horizontal-scrolling, wrapping dropdown for part selection, improving usability and readability on smaller viewports. His approach emphasized responsive web design and usability optimization, with clear, consumer-focused commit messages documenting each change. While the scope was limited to a single feature and no bugs were reported, the work delivered measurable improvements in accessibility, navigation clarity, and onboarding efficiency for users.
