What I'ved Learned

Keen insights that capture even the small user experience

Through this project, I realized that the key to delivering high-quality UX results lies in truly listening to the user. It became clear that every aspect of design, from high-level planning decisions to small details like component size and placement, must be based on the user's experience. Through user testing and continuously refining the screens based on the insights allowed me to experience the process of creating an impactful product.

Next Step

Balancing Visual Appeal and Usability

Instead of using typical fueling design patterns, I introduced fresh visual effects for a new experience. However, I had to ensure these changes met user needs and didn’t affect usability. The challenge was balancing core fueling functions with visual differentiation. Moving forward, the goal is to blend usability and design for a refined, purpose-driven final product.
