I'm Brian Casel, a full stack product builder who's gone all-in on AI-first development. Building with AI isn't just hype—it's leverage. It's transforming how we create software products, and I'm here to show you why mastering these techniques now will define who wins in the next decade. Each week, I share: - What's actually changing in our craft (not just what's trending) - Practical AI building techniques you can use today - Real lessons from shipping AI-powered products This isn't about chasing the latest models or buzzwords. It's about understanding how AI fundamentally changes what's possible for builders. If you're a developer, designer, or product builder who wants to stay ahead of the curve without getting lost in the noise, you're in the right place.
