Avoided thousands in costs by expediting firmware upgrades, engineering change orders, and instituting physical inspections to expand configuration core competencies at Cardenas Markets Inc.

Minimized risk exposure through critically managing the network security by adding an HTTP proxy server to block malicious and inappropriate URLs as well as monitor activity at Cardenas Markets.

Implemented WSUS patching across the enterprise.
