Ryohei Mashiko
Frontend Developer
Hi! I am a frontend developer from Japan with 4.5 years of professional experience. Currently based in London, where I have been working for over 3 years.
I enjoy turning ideas into functional applications and solving problems with technology.
I'm comfortable working with React, Vue, and Node.js, and I'm always keen to learn new technologies. While I have a professional background in frontend development, I'm also eager to explore backend technologies like Golang and Rust.
Before transitioning into tech, I spent four years in B2B account management, which has given me a solid understanding of the business side as well.
Outside of work, I have many interests. I enjoy running, cycling, swimming, watching volleyball, reading, gaming, traveling, custom keyboards, and sleeping. I also love discovering hidden gems, especially Japanese restaurants and food in London.
