What I'm looking for

I seek a security-focused role where I can lead risk reduction, implement strong governance, mentor teams, and drive infrastructure resilience within a growth-oriented organization.

I am an information security specialist with extensive experience in security policy development, IT risk management, vulnerability assessment, and infrastructure optimization. I have led cross-functional teams, managed enterprise risk registers, and delivered training and executive reporting that improved compliance and reduced exposure.

My background spans information security management, disaster recovery, incident response, and large-scale infrastructure delivery across multi-data-center environments. I combine hands-on technical skills with governance and stakeholder engagement to recommend and implement pragmatic security controls and resilient infrastructure solutions.
