Worked on the NYCU-Service-Learning/nanao-system repository, focusing on frontend development and UI stability over a two-month period. Addressed layout issues by dynamically calculating content height to prevent header overlap and removed redundant padding to improve consistency, using CSS to enhance readability and reduce visual glitches. Improved user experience by refining hover feedback for interactive elements, updating glow effects for clearer interaction cues, and resolving homepage layout gaps to ensure the container filled the viewport. Maintained clean, focused commits that prioritized maintainability and traceability. Demonstrated attention to detail in CSS and frontend engineering, delivering targeted improvements to usability and visual consistency.
