Who I Am

I'm a Senior Security Engineer with over 8 years of experience designing and deploying privileged access management and identity security solutions across enterprise environments. At CyberArk, I help organisations eliminate standing privileges, enforce least-privilege access, and respond to identity-based threats before they become breaches.

I thrive at the intersection of security architecture and hands-on engineering — whether that means designing a PAM rollout for a Fortune 500 bank, scripting a custom connector for a legacy system, or helping a cloud team adopt just-in-time access without slowing down their CI/CD pipeline.
