I design and build cloud systems and AI applications for enterprise. My background spans architecture, hands-on engineering, and the messy human work of getting technology adopted at scale.

Currently I'm focused on agentic systems, and how they help organizations turn complex technology into real business value.

While researching and designing for this current setup, I was dissatisfied with guides that were either too complex, or simplified but had security flaws.
