Modern 3D Portfolio Website Build

My goal is to launch a sleek, modern personal portfolio that showcases my work through immersive 3D experiences. The site should feel clean and contemporary in its overall UI, yet immediately engage visitors with interactive 3D elements on the landing page.

Key features I need integrated:
• An interactive 3D hero section that responds smoothly to mouse or touch input
• A dedicated 3D model viewer where visitors can rotate, zoom, and inspect models in real time
• Subtle, performant 3D animations that enhance navigation without slowing the site

I’m comfortable with you choosing the best-fit stack, but solutions built around WebGL-friendly libraries such as Three.js or Babylon.js make the most sense. Clean, maintainable code and lightweight assets are important so performance stays high on both desktop and mobile.

Deliverables:
1. Responsive, production-ready website files (HTML/CSS/JS or a framework of your choice)
2. All 3D assets optimized for fast loading
3. Source files and build instructions so I can update content later

Completion will be approved once the site loads quickly, the 3D interactions work fluidly across modern browsers, and the design matches the minimalist-modern aesthetic discussed above.
