As a full-time hardware and software technician for Fiscal Systems, I provisioned, repaired, and implemented proprietary C-Store POS Software and Hardware while also physically repairing some proprietary hardware. Knowledge in Linux Sub-Systems, Verifone pin pads, and fuel control systems. I also wrote technical documentation on systems that I worked on.
