Cisco networking
Cisco IOS switching and routing fundamentals, VLAN/L2/L3 troubleshooting, DNS, DHCP, VPN, SNMP, Meraki, Cisco wireless controllers, Nexus/ASA exposure, Palo Alto exposure, Cisco ACI collaboration, and the habit of proving whether the issue is ISP, cabling, switching, routing, DNS, or endpoint.
Windows domain environments
Windows Server, Active Directory, GPO, DNS/DHCP, domain-joined endpoints, file/share access, Office deployment support, user support, and practical troubleshooting across isolated or business-critical Windows environments.
Linux operations preference
Debian-style Linux is my preferred admin environment, especially apt-based systems, SSH, logs, shell workflows, hosting, systemd services, containers, scripting, and low-friction troubleshooting. On laptops, it is hard to beat a clean Linux desktop; on desktops and lab systems, I am open to experimenting.
Organic data capture
Turning normal work into useful operational data: intake facts, item status, custody, blockers, photos, documents, activity proof, health checks, and reports that show what is happening without making employees do duplicate entry.
Self-healing operations
Systems that detect drift, surface blockers, route follow-up, validate state, and improve over time through dashboards, telemetry, reminders, repair scripts, rollback notes, and proof-backed support.
Systems and workflow apps
ASP.NET Core/Razor Pages, MongoDB-backed apps, IIS/TLS, SQL Server support, Azure Blob storage, ServiceNow, SCCM, N-able scripting, PowerShell validation, virtualization practice, and NetApp storage lab work.
Field and production systems
POS and kiosk installs, ATM and drive-thru systems, WAP deployments, VoIP visits, rack/cable cleanup, workstation refreshes, public-safety and law-enforcement site support, drywall-aware install work, trenching and buried conduit, antenna mounting and aiming, CNC/shop technology context, pneumatic systems, practical PLC familiarity, and onsite closeout.
