What I'm looking for

I seek security-focused roles where I can lead incident response, strengthen IAM, collaborate cross-functionally, and grow in SOC/engineering pathways within compliance-minded teams.

I am a security-focused IT professional with 5+ years supporting high-volume production environments, identity and access management, and compliance-driven systems across the U.S., Canada, and the U.K.

At Renaissance Learning I provided Tier 1 operational security and technical support, resolved 3,500+ support tickets during peak season, maintained 92% customer satisfaction, and enforced FERPA, COPPA, and SOPPA compliance.

I investigate account lockouts, login anomalies, and phishing, escalate incidents through SOC-style workflows with forensic-quality documentation, and developed remediation steps later adopted by Tier 3 support.

I am completing the Google Cybersecurity Certificate, have hands-on experience with Azure VMs, Active Directory, VPNs, and TryHackMe labs, and bring practical mainframe exposure from an IBM z/OS apprenticeship.
