About John Fricano
I specialize in stabilizing hybrid environments by working across virtualization, cloud identity, and core network infrastructure. I’m the engineer who takes on the complex Tier 3 escalations — the ones that require deep troubleshooting across VMware/Hyper‑V hosts, Entra ID identity flow, DNS/RADIUS, and hardware-level systems.My strength is identifying the actual root cause behind outages in environments with little or no documentation. Whether it’s a misconfigured VLAN, a failing RAID controller, an ESXi host losing hardware monitoring, or an identity sync failure, I’m comfortable tracing issues across layers until the system is stable again.I’ve supported production environments through firmware upgrades, storage/RAID analysis, identity integrations (SAML/OAuth/SCIM), and disaster recovery validation. I enjoy restoring reliability, reducing escalations, and improving the health of hybrid infrastructure.Core Focus Areas:• Virtualization (VMware ESXi, Hyper‑V)• Entra ID / Azure AD & Identity Integrations• Network Operations (Meraki, FortiGate, VLAN/DHCP/DNS, RADIUS)• Out-of-band Management (iLO/iDRAC)• Incident Response & Root Cause Analysis• Disaster Recovery (Datto BCDR)Project:PhishScan — A phishing analysis tool integrating VirusTotal, AbuseIPDB, and automated SPF/DKIM/DMARC
