Curious how this was built?

This whole site — 1,900+ events, the calendar, the parks map — was built with Claude Code, an AI coding tool, by a busy mom in the margins of the day. If you've been wondering how to actually use AI to build something real, I'd genuinely love to show you how to get started.
