Building My Portfolio with AI as a Pair Programmer

I've been a full stack developer for over 7 years. I've built dashboards, APIs, real-time apps, and enterprise software. But I'd never built a proper portfolio site for myself. It was always on the list, never at the top. What changed was Claude Code. I wanted to try AI-assisted development on a real project, not a toy example. And I wanted to learn Astro at the same time. So I opened a terminal and started a conversation. This post is about what that experience was actually like. The Setup I started with an empty directory and a vague idea.
