The person behind the platform
AI full-stack engineer · YCH-YOYO team member
Known in the yo-yo community as Pocket, Zirui Qiu brings a player's perspective to building YCH-YOYO's online platform. Alongside his Destiny signature yo-yo, he connects shopping, custom design and competition review through his work as the platform's full-stack lead. His personal website brings together this journey, independent projects and explorations in AI and computer vision.

As YCH-YOYO's project owner and full-stack platform lead, Zirui connects the experience of choosing a yo-yo with the work that follows an order. His responsibilities span the storefront, accounts, checkout and order management, alongside online artwork editing, model previews and custom production workflows. He also builds tools for reviewing competition videos with the community. Across these parts of the platform, his focus is on helping players turn ideas into designs, follow their progress and learn from each performance.

Competition video review and community scoring let players revisit a routine, compare perspectives and discuss the details that are easy to miss in the moment.
Zirui began yo-yoing in 2011 and practices both 1A string tricks and 2A looping. Known as Pocket, he brings that experience to the YCH-YOYO team and his Destiny signature yo-yo. Competition and judging remain part of his connection to the community.
