Served as Lead Network Engineer supporting 2 Data Centers, 2 Campus Environments, 3 Labs, and 1200+ retail locations. Environment included large footprint of Meraki devices including appliances, switches, and access-points. Planned and implemented Cisco Application Centric Infrastructure (ACI) for both Data Centers including 2 spines, 4 leaf’s, and 3 APICs per Data Center.Move firewall configurations from the Cisco ASA to Cisco Firepower. For this effort both client and clientless VPN remained on the Cisco ASA. Upgraded two legacy Cisco routers with ASR1001-HX to support DMVPN hubs for each Data Center. These hubs are supporting 400+ remote retail locations. Upgraded two legacy Meraki MX100 switches with Meraki MX450 switches to support a growing footprint of Meraki MX Appliances for 450+ retail locations. Used automation skills including Ansible, API calls, and Python automation code to optimize the following process efficiencies/improvements: 1. Using Ansible Playbooks implemented YAML code to automate the procedure to remove and add Cisco IOS configuration to transition from MPLS to Broadband circuits. This Playbook reduced the time required to add required configurations and removed un-needed configurations to complete this conversion. Reduced installation time by 92% (from 25 minutes to 2 minutes) by creating Ansible playbooks. The automation implemented also allowed for simplified operational improvements by allowing the ability to move this task from Network Engineers to staff who have no network experience. 2. Other automation achievements included implementing automation to update Cisco and Meraki devices to streamline several repetitive tasks including DHCP reservations, configuration backup, interface configuration, etc. and moving these tasks to staff who have no network experience. 3. Utilize API's on Meraki appliances, switches, and access-points, to automate tasks including updates, conversions, deployments, etc.
