  1. Built a structured design process from ambiguity: Starting from open-ended Crazy 8s ideation, I narrowed ideas down through prioritization, iteration, and feedback. This practice strengthened my ability to move from uncertainty to a clear, well-reasoned design direction.
  2. Developed a real understanding of redesign case studies: Redesigning an existing product helped me learn how to evaluate current systems, identify gaps, and justify design decisions within real constraints, key skills for UX case studies.
  3. Grew rapidly through independent work: Working solo pushed me to own every stage of the process, from ideation to execution. While collaboration is valuable, this project accelerated my skill development by challenging me to problem-solve independently and push beyond my comfort zone.
