- ERP Fundamentals (SAP Materials Management)
- Access Control & Incident Response
Home Lab Projects
Self-directed infrastructure builds — real environments configured, broken, troubleshot, and documented end to end. Part of a 7-lab IT/cybersecurity series running through December 2026.
Active Directory & Windows Server Home Lab
Built a full AD domain in VirtualBox — domain controller, OU/group structure, Group Policy (password policy, drive mapping, restrictions), DNS, DHCP, NTFS/share permissions, and a domain-joined Windows 11 client. Verified end-to-end with real troubleshooting documented.

Microsoft 365 / Entra ID Lab
Cloud identity and access management on a Microsoft Entra ID tenant with a verified custom domain — department-based security groups, a Conditional Access policy requiring MFA for higher-risk staff (tested in report-only mode), and RBAC delegation of user administration away from the Global Admin account.

Networking Lab
VLANs, DHCP/DNS, firewall rules, routing, and Wireshark packet analysis — building and troubleshooting a segmented network from scratch.
