Yosuke Sato

A web developer in Japan. My first career as an engineer is working for one of the major banks in Japan. As a bridge engineer, I worked on defining the specifications and doing system consultations for foreign customers. In order to be a full-stack developer, I started PHP and JavaScript programming at a start-up company where I successfully released many websites. For more brushing up my technical skill, I worked at leading tech companies in Japan. Since I spent many years working with not only developers, but also marketers, web designers, and business layer stakeholders, I can provide systems focusing on the best UI/UX.

Currently, I’ve been enjoying development with TypeScript, React, Vue, AWS, and GCP.
