The journey

How I got here

The full story →
  1. 2009 Licensed in New York. Manhattan residential — cold calls, open houses, a market learned block by block.
  2. 2014 Founded my own firm. Broker to broker-owner. The business taught discipline; the books taught the rest.
  3. Daily Swim. Bike. Run. Triathlon keeps everything honest. Every session on Strava, live, below.
  4. Always Faith and the library. Scripture, biographies, craft — where the miles and deals get their meaning.
  5. Now Shipping software. Vibe coder, designer, data architect — building this platform with AI, in public.

The gap isn't talent or budget—it's method. This book gives you the operating discipline that turns a coding agent from an impressive demo into a reliable teammate who ships real software. You'll learn to onboard an agent, hand it work in tight iterations, verify everything it claims, and catch failures before they reach production. You'll build review gates, telemetry, and layered defenses that let you move fast without moving recklessly. Written for people who need working software, not a computer science degree, it treats you as a founder managing a capable-but-junior hire. By the end you'll ship production code alone—and trust what you shipped.
