As a Game UX/UI Design Intern at Tanbii, I worked collaboratively with two other interns to research and propose enhancements to various sections of the Tanbii mobile app. My contributions included refining the Achievements menu to improve user engagement, optimizing the Carbon Tracking menu for better clarity and usability, and conceptualizing a Referral feature to drive user acquisition and social interaction. Through this experience, I developed skills in UX research, wireframing, prototyping, and UI design, while gaining hands-on experience in game design principles and sustainability-focused gameplay mechanics.
