Building Kyuto Fit: A Case Study in Glassmorphism

When I set out to build my personal brand website, I had three core goals:

1. Elite Performance - Sub-second page loads, perfect Lighthouse scores
2. Playful Aesthetics - Glassmorphism with bouncy micro-interactions
3. Developer Experience - Clean architecture that's easy to maintain

Tech Stack

I chose Next.js 16 (App Router) for its server components and built-in optimizations. The entire site is statically generated at build time, resulting in blazing-fast page loads.

For animations, Framer Motion was the obvious choice. The spring physics and gesture support made it trivial to add the bouncy, playful feel I was going for.

Design System

The glassmorphism aesthetic required careful attention to:

• Backdrop blur - Using backdrop-blur-xl with subtle transparency
• Border gradients - Pink/cyan accents on glass cards
• Layered shadows - Multiple shadow layers for depth
• Micro-interactions - Hover states with spring animations

Performance Optimizations

Despite the heavy use of animations and effects, the site maintains excellent performance:

• Code splitting - Dynamic imports for heavy components
• Image optimization - Next.js Image component with WebP
• Font optimization - Self-hosted fonts with font-display: swap

Lessons Learned

Building this site taught me that performance and aesthetics aren't mutually exclusive. With the right tools and careful optimization, you can have both.

The key is to:

• Use CSS transforms for animations (GPU-accelerated)
• Lazy load non-critical components
• Minimize JavaScript bundle size
• Leverage server components where possible

What's Next?

I'm planning to add more interactive experiments to the Lab section, including:

• Real-time collaboration demos
• WebGL particle systems
• AI-powered code playgrounds

Stay tuned!
