Security Philosophy

Offense informs defense. You can't build effective security without understanding how attackers think. Every engagement starts with an adversarial perspective — what would I do if I wanted to break in?

Context is everything. Security isn't one-size-fits-all. A startup's threat model differs from a bank's. I tailor every approach to your specific risk profile, business constraints, and threat landscape.

Automation amplifies expertise. Manual testing catches what tools miss, but tools scale what humans can't. I build custom workflows (Claude Code, custom scanners) to maximize coverage without sacrificing depth.

Family drives purpose. Married with three kids and a fourth on the way. Security isn't just my job — it's how I provide for my family. Every engagement matters. Every vulnerability found protects real people.

Let's Work Together

Whether you need a penetration test, security audit, AI guardrails, or team training — I bring 10+ years of battle-tested expertise to your toughest challenges.
