Key Teams
The key teams are as follows. Mercari has many teams outside of these.
Backend Team
Mercari’s Backend Team is currently entering a major transition phase. The Mercari app has been growing at an incredible pace ever since its release and is now the largest C2C platform in Japan. The Mercari API codebase has also expanded in line with the service’s growth and the variety of challenges faced. As we anticipate our service to grow at an even greater speed in the future, we are aiming to use microservices to help achieve Mercari JP’s mission.
Frontend Team
Mercari’s Frontend Team develops products using web frontend technology made with Javascript/HTML/CSS, rather than native apps. With the recent increase in attention towards topics like PWA and SPA/SSR, we at Mercari are aiming to strengthen the company’s product development using modern web technology as a base.
Mobile Team
Mercari’s mobile team is currently working on a major re-architecture of the Android/iOS apps in order to create a structure where they can conduct further large-scale development while maintaining speed and security. The team is also working on various other projects, such as developing new features and improving the UX. The mobile team consists of members from many different countries; we hope to unlock the potential of this diverse team in order to make even greater achievements.
