Books
I’ve authored several IT certification study guides published by Wiley/Sybex and Manning Publications, including Amazon bestsellers. My Wiley titles have sold 100,000+ copies ($2.5M+ publisher net) — including bestseller-tier AWS Solutions Architect Associate (SAA-C03, 17k+) and AWS Cloud Practitioner (CLF-C01, 32k+). There’s a massive gap between passing a certification exam and actually surviving in a production environment. I write books that bridge that gap. Yes, these guides will help you pass the exam—but my real goal is to give you the fundamentals you need to architect resilient systems and troubleshoot them when they inevitably break.

You'll learn how to actually design resilient, high-performing architectures that survive real-world traffic spikes, and how to balance cost with security without letting vendor lock-in dictate your design.
