Kazuyuki Motoyama is a designer-founder with 13 years of experience blending web, DTP and front-end engineering (HTML/CSS/JavaScript/PHP) into polished product experiences. He co-founded Spinners Inc. and runs Jellyfish Design, applying a product-minded design practice honed at Cookpad and Hatena where he led mobile and multi-platform app design efforts, including smartwatch and global service work. Comfortable shipping both visuals and implementation, he has a track record of taking features from concept through interface and front-end code. Based in Chiyoda, Japan, he pairs formal design training from Nagoya City University with hands-on engineering roots from an early creator role, making him equally fluent with pixels and production constraints. An understated strength is his longevity across consumer apps and platform integrations, showing skill in evolving designs for rapidly changing mobile ecosystems.
