I built a Rails app from scratch using only Claude Code as my AI coding partner. Here’s the full, unedited session showing my real workflow for AI-augmented development.
In this live coding session, I start a brand new Ruby on Rails SaaS app and build user authentication from zero using Claude Code. But this isn’t a “how to build auth in Rails” tutorial. It’s a deep look at how I actually use Claude Code to drive development: plan mode, custom skills, TDD workflows, iterating on Claude’s memory, sub-agent code reviews, and more.
