Rockstar🎓
Top SchoolMasahiko Ashizawa is a seasoned technology leader and CTO with 15 years of hands-on experience building internet applications, middleware, and network infrastructure across startups and product-focused companies in the Greater Tokyo Area. He combines early technical curiosity—coding since age nine—with practical entrepreneurship, founding Aileron-INC to prototype VR systems, recruitment platforms, and Indonesian market crawlers. A pragmatic polyglot engineer who often uses Ruby on Rails for rapid prototyping, he has a track record of architecting bespoke web frameworks, subscription commerce features, and media systems. Comfortable shifting between low-level system design and product-facing prototypes, he brings both strategic vision and the willingness to roll up his sleeves to ship working solutions. Notably, his background includes mobile and embedded server work as well as building tools for music distribution and royalties, reflecting a wide technical breadth beyond typical web stacks.
