"Security isn't about breaking systems. It's about understanding them well enough to build them stronger."

Engineering Security at
Enterprise Scale

I simulate realistic cyberattacks to identify weak points in your Web Applications, APIs, Cloud Environments, and Internal Networks before malicious actors do.

I specialize in Security Engineering, Product Security, Cloud Security, and Offensive Security, building secure-by-design enterprise environments through automation, detection engineering, identity security, vulnerability management, and governance.
My experience spans Microsoft Defender XDR, Azure, Entra ID, Intune, application security, DevSecOps, and enterprise risk management. I enjoy solving security problems by combining offensive thinking with scalable engineering solutions.
