About Me

Hello! I'm YUMA Kitamura, an application developer and engineering manager with over 8 years of experience in building modern web applications. I'm passionate about creating clean, efficient, and user-friendly interfaces.

Currently, I work as an Engineering Manager at wevnal inc., where I lead a team of talented developers in creating innovative solutions for our clients. I specialize in frontend development with React, Vue, and TypeScript, but I'm always eager to learn new technologies and frameworks.

When I'm not coding, I enjoy contributing to open-source projects, writing technical articles, and sharing my knowledge with the developer community. I also enthusiastically lead in organizing technical conferences (FlutterKaigi, Frontend Conference in Kansai region and etc).
