From support to security.
I work at the intersection of secure systems and day-to-day operations. At Sonalysts, I support security and compliance for classified, air-gapped, and enterprise environments, with a focus on Windows Server hardening, patching, vulnerability remediation, and DoD cybersecurity requirements.
My earlier work spans SOC alert triage, endpoint and identity support, large-scale IT/AV deployments, and ETL development. Across those roles, I’ve paired hands-on troubleshooting with documentation, user support, and training.
