Device reconciliation tool
Built with: vanilla HTML, CSS, and JavaScript in a single file, with no build step or backend. Deployed to internal network-attached storage through an automated git sync.
A browser-based tool that cross-references device inventory across multiple management platforms to catch devices that fell out of sync, went stale, or dropped off monitoring. The tool matches records with a serial-first engine that falls back to hostname and friendly-name bridges, then flags mismatches, stale check-ins, missing endpoints, and naming inconsistencies for a technician to review each month.
