What I'm looking for

I’m looking to own cybersecurity risk, compliance (NIST/ISO/FISMA), and remediation workflows—partnering across IT and stakeholders to reduce vulnerabilities, meet SLAs, and continuously improve security posture through measurable execution.

I’m a Cyber Security Analyst focused on turning compliance requirements into real protections for mission-critical systems. Across federal agencies, I support security audits and assessments aligned to NIST Risk Management Framework (RMF), ISO 27001, and FISMA, while implementing and authoring security authorization documents.

In my most recent role, I protected IT systems from phishing threats, supervised the implementation of security controls, and ensured FISMA compliance with mandated policies. I implemented risk assessments and vulnerability scans, addressed 42% of identified weaknesses, integrated vulnerability data with SIEM and ticketing systems, and helped drive a 100% compliance result across required controls.

Earlier, I oversaw the security posture of 40,000 systems for DOC OIG—implementing over 900,648 patches—and led ISO 27001 implementation with a 25% reduction in security incidents and a 95% compliance rate. I’ve also built resilience through disaster recovery testing and developed security awareness programs, then supported operations as a Help Desk Manager and IT Manager with measurable improvements in ticket closures, delivery, uptime, and security governance.
