Senior🎓
Top School田中佑樹 is a seasoned technology leader and CTO with 14+ years of experience building product-led organizations and scalable web services, currently leading kubell after a long tenure at Chatwork. He began as a full-stack engineer (Java, PHP, Scala, TypeScript/React) and steadily moved through EM and cross-functional product leadership to run the entire Product Division as an executive. He combines hands-on cloud and data experience (AWS, TreasureData, BI tooling) with deep operational rigor in security—having founded a Product Security team, run Bug Bounty, and institutionalized vulnerability scanning and encryption guidelines. A builder of org-level capabilities, he launched a DevHR practice to align engineering and people processes, improving hiring, onboarding, and inner communication. He mentors through active 1:1 coaching and still does consulting and development side projects, demonstrating both technical curiosity and talent development at scale. His background in mathematics (Sophia University) underpins a data-driven approach to product and organizational decisions.
