Practitioner AI: building real things, documenting what works, and sharing what I learn — because the most useful AI voices belong to experienced practitioners.
About
I spent my career as a healthcare CIO — leading technology strategy across some of the largest diagnostic and health system organizations in the country. Along the way I learned that the best technology decisions come from people who understand both the problem and the tools.
That belief is what drives my current focus on AI. Not the hype. Not the theory. The practice. I am building real things, documenting what works, and sharing what I learn — because I think the most useful AI voices right now belong to experienced practitioners, not just technologists.
My AI journey began with a simple question: can I actually build something useful without a development team? The answer turned out to be yes — but only once I started thinking like a builder instead of a user.
