Remember writing code by hand? Today I work entirely with agents. The shift happened fast — faster than any of us expected.
I've been shipping products for over 20 years. I've seen tech come and go. But this is different. AI isn't just a better tool. It's a new way of working.
That transition isn't easy. The noise is overwhelming. It's hard to know what's worth learning and what's hype. I felt that too. So I started documenting what actually works — the workflows, the thinking, the practical stuff that moves real projects forward.
That's Builder Methods. Thousands of developers and founders — from seasoned pros to ambitious newcomers — have come here to learn, stay sharp, and work at this new level. No hype. No hand-holding. Just practical training for people who take their craft seriously.
If that's you, you're in the right place.

The shift to AI-first development isn't just individual — it's organizational. I (Brian Casel) work with product teams, engineering leaders, and executives to accelerate adoption, align workflows, and unlock the speed and ambition that AI-first building makes possible.
