Build me a clean, minimal personal website for a developer portfolio, blog, and small web experiments playground.

I want it to feel fast, polished, and simple, with a strong focus on good typography, whitespace, and mobile friendly layout. It should have a homepage, about style sections, a blog that can load posts from Markdown or MDX, and the usual SEO basics like sitemap, robots.txt, and structured data. Please also add RSS feed support and automatic Open Graph images for posts and pages.

Use Next.js with the App Router and Tailwind for styling, and keep the design understated, modern, and easy to customize. If you need to look up current docs online for anything, go ahead. I’d also like analytics support for Vercel Speed Insights and Web Analytics, and the site should be ready to deploy cleanly.
