Modern Responsive Portfolio Website

I want to launch a sleek, modern-style portfolio site that looks and feels flawless on phone, tablet, and desktop alike. All code must be hand-written in clean HTML, CSS, and vanilla JavaScript, with performance kept front of mind and a light touch of tasteful, fluid animations to bring key elements to life.

Core pages I need are:
• Home
• About Me
• Contact

Please structure each page semantically, keep the stylesheet organized, and comment your JavaScript so future tweaks are straightforward. I will need the full, well-documented source code when we finish, and I’m happy to provide rapid feedback—multiple revision rounds are expected until everything meets the brief.

If this sounds like the perfect fit, let’s get started.
