Summary
👤
Senior🎓
Top SchoolJun Kasamatsu is a seasoned technology leader and CTO based in Yokohama with 12 years of experience building end-to-end web products from inception to release. He transitioned early from an SES role into web engineering and has worked on pioneering consumer-facing projects like Chromecast apps and chatbots during their formative stages. Equally comfortable with React/Vue front-ends and low-level backend concerns—TCP socket communication, IaaS selection, and system architecture—he is an all-rounder who shapes both product and infrastructure. After senior engineering roles at Mobils and NextGen, he joined Common Creation as Chief Technology Officer in 2021, guiding technical strategy and delivery. His background in Information System Engineering and hands-on history with emerging platforms give him a practical knack for turning experimental ideas into reliable production services.
