Security Architecture Leader

IT Professional since 2002 · 20+ years experience

CISSP CCSP

I'm a security architecture leader with over two decades of broad IT experience spanning infrastructure, data, and cloud disciplines. My career began in 2002 and has taken me through hands-on roles as a systems administrator and systems engineer before moving into database administration and ultimately executive leadership as a Chief Technology Officer.

Today I manage a team of security architects, translating complex threat landscapes into pragmatic, scalable controls that protect the business without impeding it. I'm deeply passionate about security architecture as a discipline — the intersection of risk, design, and engineering where good decisions compound over time.

This wiki is my personal reference and knowledge-sharing platform, covering the architectural patterns, frameworks, and tooling I rely on day-to-day.
