About Me
Hi, I'm Joji—a Fullstack Web Developer passionate about building modern, scalable, and interactive web applications. I specialize in React, Next.js, TypeScript, and tools like Tailwind CSS and Firebase to create seamless digital experiences that balance performance and visual polish.
Whether developing single-page apps or fully integrated platforms, I focus on clarity in code, thoughtful UX, and clean, maintainable architecture.
Beyond Code
Music
As a musician, I understand rhythm, flow, and storytelling—skills that naturally inform my approach to UI and interaction design.
Meditation
My yoga meditation practice supports a calm, focused mindset that helps me stay present, thoughtful, and resilient in fast-moving dev environments.
I'm always looking to collaborate on meaningful, forward-thinking projects. Let's connect and build something exceptional.
