How to Build Million-Dollar SaaS Applications Using Claude Code (Opus 4.6 & Sonnet 4.6)

Why This Course Exists

In 2026, the rules of software development have fundamentally changed. Solo developers are shipping products that previously required teams of 20. Startups are reaching $1M ARR in months instead of years. The secret? Claude Code — the AI-powered CLI that transforms how you architect, build, test, and deploy software.

This is not a theoretical course. You will build a real, production-ready SaaS application from scratch using Claude Code with Claude Opus 4.6 and Claude Sonnet 4.6. Every chapter includes hands-on projects, real code, and battle-tested strategies from developers who have shipped AI-built products to thousands of paying customers.
