If you're here, you came to build AI agents that actually work — not in a notebook, not as a demo, but as deployed software running for real users. The Stack is a self-paced curriculum for that. The lessons are built around real shipped agents I run in production, not toy examples. The stack is real (Vercel, Railway, Supabase, Anthropic, LiveKit, Deepgram), the patterns are real, and the design philosophy underneath is its own working vocabulary you'll absorb as you go. Course One starts in the Classroom tab. Lesson 1 — The Repository — is the foundation. Every lesson opens with a Definitions section so you can read the rest fluently. Both the code vocabulary and the framework vocabulary get the same treatment: short, plain-language, side by side. A few things to know about this community: No leaderboards-as-status. The leaderboard exists; engagement happens in the lessons, not in points-farming. Questions are welcome and direct answers are the norm. If you're stuck, post in General Discussion. Other builders will help. So will I. No pitching, no recruiting, no DMs trying to sell each other things. The Stack is for the work, not for the side hustles around the work. I'm Christopher. I run ROSE Corp out of Jackson Hole. I've been building agents for a couple of years and writing about the design philosophy underneath them in a series of working papers. The Stack is where the building practice and the writing meet. Lesson 1 is up. See you in Classroom.
