Database migration
A rehearsed database cutover
Moved the business database and attached files to a dedicated server. Rehearsed the move and checked rollback readiness before cutover.
About 414 GB moved with checks between phases.
Neal Spangler
System Administrator
I manage IT for a sign and print manufacturer, from user support and networking to Linux servers, backups and production systems.
I'm based in Dayton, Texas, and available for remote work or hybrid and on-site work around Houston.
Start here
Three examples of how I plan, make and check a change.
Backups and recovery
Checked the copies behind the backup jobs
Added snapshot history and a second NAS, and configured an offsite transfer. Replaced unreadable database dumps and checked copies separately.
Separate checks for shared-file backup copies.
Mac management
A pilot before the fleet rollout
Proved enrollment on a reset pilot, then moved the other Macs in place. Scripts read back settings after applying them.
12 Macs on one management system.
63devices I run and secure
24cameras under automated health checks
400+cutter programs that load from a scan
6 yrsrunning all IT for a 12-person office
What I do
Infrastructure
Servers, storage, backups and the cloud platform.
ProjectsSecurity and network
Assessments, hardening, phishing response and the network itself.
ProjectsAutomation and AI
Scripts, scheduled jobs and AI agents with command checks.
ProjectsShop floor
Printers, cutters and the PCs that drive them.
ProjectsAutomation and other work
Automation & AI
Scan a work order to load the cutter program
Operators scan a code on the work order instead of typing every cut position.
Automation & AI
AI agents with command limits and approval checks
Claude Code and Codex handle remote tasks with approval checks and command-blocking rules enforced outside the model.
