Cybersecurity practitioner and systems professional with experience spanning security operations, detection engineering, vulnerability management, infrastructure, ERP systems, and technical documentation.
My work focuses on building, validating, and documenting practical security environments that demonstrate how defensive technologies operate together—from network segmentation and centralized logging to intrusion detection, alerting, investigation, and remediation.

I am currently expanding the Hupfen Security Lab with projects focused on:
- Detection development and validation
- Structured security telemetry
- Splunk alerting and investigation
- Threat hunting workflows
- Incident response documentation
- Security engineering and control testing
I publish practical cybersecurity articles that explain the reasoning behind the projects documented in my GitHub repositories.
My background includes cybersecurity, technical support, systems analysis, ERP implementation, financial operations, and technical content development.
That combination allows me to approach security work from both a technical and business perspective, with particular emphasis on operational risk, documentation, repeatable processes, and clear communication.
