Seven years of enterprise IT operations, now channeled into building production-grade infrastructure from scratch. The Alliance Fleet is a 25+ service homelab: SSO for 15+ apps, SIEM with automated threat response, full observability pipelines, local AI inference, and 58 automation workflows. All documented, all running.

Professional Alignment Matrix

Domain Enterprise Experience Alliance Implementation
Identity (IAM) Active Directory, Google Workspace, user access governance across 200+ users. Authentik SSO: centralized OIDC/SAML with MFA enforcement across 15+ services. Full audit trail.
Infrastructure Backup solutions, patching, enterprise imaging, macOS/Windows fleet management via JAMF Pro & Intune. 3-node Proxmox VE cluster with Corosync quorum, ECC memory for data integrity, NVMe Gen4 storage.
Networking Enterprise VPN, firewall policies, DNS management, WAN optimization. 4-VLAN segmentation (Mgmt/Services/IoT/DMZ) via UniFi Dream Machine with static-only trust zones and inter-VLAN firewall rules.
Security Endpoint protection, compliance audits, Tier III incident triage and escalation. Wazuh SIEM: brute-force detection, FIM, log aggregation. 58 n8n workflows for automated threat response.
Observability Monitoring dashboards, SLA reporting, alerting thresholds, capacity planning. Telegraf → InfluxDB → Grafana pipeline. 10-second metric resolution. Used for real incident forensics (VFIO lockup RCA).
Remote Access Enterprise VPN, Zscaler, conditional access policies. Tailscale zero-trust mesh with subnet routing, ACL policies, and no exposed ports.
