- Support deployment scripts, local environment configuration, service startup order, rollback process, and release checklists.
- Validate P98 gateway/card reader behavior for online approvals, encrypted offline queueing, retry, and no-double-charge scenarios.
- Integrate and test Epson TM-m30 receipt printer, USB cash drawer, rugged Android tablets, and KDS devices in realistic restaurant workflows.
- Own nightly encrypted backup validation to on-site NAS/local corporate network, including restore testing.
- Support local network setup and troubleshooting for fixed IPs, firewall rules, VLAN considerations, SignalR connectivity, and device reliability.
- Coordinate UPS/graceful shutdown configuration for the on-site server where applicable.
- Run end-to-end technical testing from POS to API to PostgreSQL to KDS to receipt printer/payment gateway.
