Ryugo Kubota
Story
STATUS // ONLINE

I went independent as a freelance engineer right after graduating. Thrown into real projects with no roadmap, I learned to see things through and to drive my own work forward, one engagement at a time. Driven by a love of taking on the unknown, I chased new skills and efficiencies relentlessly — broadening from frontend to backend to infrastructure and growing into a full-stack engineer. Recently I've brought AI into my development work to deliver performance to companies more efficiently. A fascination with working abroad led me to start learning English three years ago, and I now have hands-on development experience in English. Having worked across 0→1 launches, growth-stage scaling, and large-scale operations, I can adapt to a wide range of engagements.
