AlmaLinux 9 → 10 Migration
Led an enterprise OS upgrade using the ELevate tool. Resolved kernel driver blockers and configured SSSD for seamless short-name Active Directory logins.
I design, deploy, and manage the systems your business runs on — full-stack network & wireless design across Cisco, Meraki, Fortinet & UniFi, plus surveillance, access control, and the servers, monitoring, and cloud behind them. Two decades keeping complex infrastructure fast, stable, and secure.
Specialized services to design and secure your network, protect your premises, and keep your operations running without surprises.
End-to-end network and Wi-Fi design across Cisco, Meraki, Fortinet and Ubiquiti UniFi — gateways, switching, VLANs, PoE, racks and structured cabling, finished with wall-to-wall wireless validated by on-site surveys and heatmaps. Deep experience deploying Wi-Fi in healthcare facilities, offices, and multi-site environments.
Perimeter and internal defense — Fortinet FortiGate High Availability, NetScaler, VPN, segmentation, and firewall hardening that keeps threats out.
Cross-platform server and endpoint management — Windows Server (AD, DNS, DHCP, Group Policy), enterprise Linux (AlmaLinux, RHEL), and macOS fleets — with OS migrations, directory integration, and patching.
Observability that actually tells you what's wrong — Zabbix deployments, custom templates, macro-based exclusions, and automated alerting.
Exchange Online and mailbox migrations, Microsoft 365 administration, Entra / AD integration, and PowerShell-driven troubleshooting.
IP video surveillance and door access — camera coverage design, NVR/VMS setup, PoE, badge readers, and door controllers, all integrated with your network.
Ongoing management, automation, and a steady hand for the hard problems — from scripting and documentation to incident response.
A selection of real projects — the kind of infrastructure work that has to go right the first time.
Led an enterprise OS upgrade using the ELevate tool. Resolved kernel driver blockers and configured SSSD for seamless short-name Active Directory logins.
Optimized an enterprise monitoring environment with custom template development and configured MS Teams Adaptive Cards for actionable alerting.
Diagnosed and resolved transient communication failures during an enterprise Exchange mailbox migration using targeted PowerShell diagnostics.
Full-stack network design for a 5,685 sq. ft. suite — UniFi gateway, PoE switching, VLAN segmentation, and a site-surveyed wireless layout with seamless roaming across the floor.
Designed and deployed pervasive wireless for a clinical environment — full-coverage AP layout, seamless roaming for mobile devices, and segmented VLANs for staff, medical equipment, and guests.
Rolled out IP camera coverage and door access control across a multi-suite facility — PoE camera cabling, NVR/VMS configuration, and badge-based entry with per-door scheduling.
Stood up and modernized Windows Server environments — Active Directory, Group Policy, DNS/DHCP, and Hyper-V — with clean version upgrades and hardened, well-documented configurations.
Standardized and secured Mac fleets — MDM enrollment, configuration profiles, app deployment, FileVault encryption, and directory binding for a consistent end-user experience.
No surprises, no downtime you didn't plan for.
A discovery call and review of your current environment, goals, and constraints. You get a clear scope and a fixed quote.
A documented rollout plan with rollback steps, scheduled around your business. Change-managed, tested, and communicated.
Handover docs, monitoring in place, and ongoing support so it keeps running — long after the project ships.
Whether it's a network redesign, a high-availability migration, or a monitoring overhaul — tell me what you're working with and I'll reply within one business day.
