He has independently launched multiple consumer and developer products—some exceeding 10,000 DAU—and open-sourced polished UI/animation components like KYAnimatedPageControl and Longinus image library. Comfortable across native iOS, SwiftUI, serverless backends, Web3 and AI, Qitao blends deep systems-level optimization with elegant UX animation craftsmanship. Based in Hong Kong, he’s equally at home authoring technical guides and building Mac developer tools, reflecting a rare mix of product instincts and low-level engineering.
