Hi, I'm Mun

I create responsive web applications using modern technologies like React and Next.js. Passionate about creating intuitive user experiences through clean code.

About Me

Hello! I'm Mun, a japanese passionate frontend engineer with 8+ years of experience creating responsive, user-friendly web applications. I specialize in modern JavaScript frameworks like React and Next.js.

While frontend is my primary focus, I'm also proficient in backend development with Node.js, Express, and C#.NET. I've built several full-stack applications that seamlessly integrate robust server-side logic with intuitive user interfaces. My experience with RESTful APIs and database design allows me to tackle projects from end to end.

When I'm not coding, you can find me gaming, reading riding horses, or experimenting with new web technologies. I'm always eager to learn and grow as a developer.
