Background
About Ryudai Mamiya
Marketing and data strategist with a background in computer science and AI. I specialize in bridging technology and business, having led cross-functional projects at NTT DOCOMO including the company’s first advertising PoC, data governance design, and product development for the in-house ad network. Known for turning ambiguity into action, I build scalable solutions by aligning legal, technical, and business stakeholders. My strength lies in structured problem-solving, curiosity-driven exploration, and an ability to translate data into real marketing impact—especially in privacy-sensitive, high-complexity environments.
