Yu is a product designer I worked with at PayPay on several QA projects. He showed great professionalism and attention to detail—from pixel checks to process improvements. When design and development misaligned, he calmly found practical solutions with the team. His suggestions for bug fixes and optimizations boosted both product quality and team efficiency. A reliable teammate, Yu consistently raises the standard of any design outcome.
