Summary
👤
Senior🎓
Top SchoolKenta Tsuji is a founder and technology leader with over a decade of hands-on experience building consumer apps, game backends, and ad systems, currently serving as CEO of Proxyworks and CTO at Vivivit. He has repeatedly moved ideas from prototype to product—co-founding Nohana within a corporate innovation center, incorporating it six months after launch, and later leading server and infrastructure design for mobile games and portfolio-matching services. Comfortable across the stack, he has shipped iOS/Android clients, backend APIs in Ruby, Go, Node.js and PHP, and run DevOps on AWS with CI/CD practices. As an executive CTO and CHRO he combines technical problem-solving with hiring and team management, using practices like one-on-ones and KPT to scale teams. Based in Tokyo with an MTech from Ritsumeikan University, he blends startup grit with a track record of operationalizing automation (e.g., automated typesetting and billing migrations) that few product founders personally implement.
