What I'm looking for

I'm looking for a remote role combining hands-on security and infrastructure ownership with technical leadership, architecture, project ownership, stakeholder interaction, and team coordination.

I've supported large-scale enterprise tooling and automation at Atos, where I managed monitoring-agent lifecycle activities, automated deployments and remediation, and acted as a technical point of contact for monitoring and management tools.

I developed PowerShell and Bash workflows that reduced 120 FTE hours in deployment and validation work. I also built self-healing capabilities for approximately 1,900 MDR agents, reducing weekly agent failures from about 130 to 6 and eliminating approximately 62 recurring FTE hours per week.

During a Kansas City Southern engagement, I analyzed the SCOM 2019 environment, extracted monitoring data with PowerShell and SCOM Shell, and produced reports to support migration planning to Dynatrace.

I'm now performing independent cybersecurity consulting, conducting security reviews, control mapping, evidence review, gap analysis, and remediation reporting using NIST guidance and CIS Controls. I’m interested in remote work that combines hands-on technical ownership with leadership, architecture, stakeholder interaction, and team coordination.
