Security engineer focused on AppSec, cloud security, and scaling enterprise security programmes

Security engineer focused on AppSec, cloud security, and scaling enterprise security programmes in complex environments. I build and improve security capabilities across large-scale systems, with a focus on practical security engineering, visibility, and operational governance. My earlier work includes digital forensics and systems security, including OS internals and malware analysis, which continues to inform my approach to modern security problems.
