Build me a clean personal portfolio website in a single HTML file.

I want it to feel polished and simple, with a nice landing section for my name, a short intro, and a few sections like about me, skills, projects, and contact. Make it easy to read, mobile friendly, and visually attractive without going overboard. Please include a navigation bar that lets people jump to each section, a place for project cards or links, and a contact area with email and social links.

Keep it lightweight and easy to edit later, since this is for a GitHub Pages style site. Use sensible placeholder content where needed, but make the layout feel like a real portfolio someone could use right away. If you need anything from current best practices, feel free to look up current docs online.
