Security Engineer & Ethical Hacker
I started out building software and running IT infrastructure, now I spend my time breaking it apart to see where it gives, then closing those gaps for a living. Network perimeters, cloud identity, DevSecOps pipelines, all of it.
From code
to defense
I spent years building software and managing IT infrastructure before moving into security full time.
That background gives me an attacker's read on systems and a builder's instincts for how they're put together, which is a decent combination when you're trying to find the weak point before someone else does. I spend a lot of time translating that into terms both engineers and the business can act on.
Right now I'm focused on cloud security, identity protection, and SIEM-driven threat detection in enterprise environments.
