Geoffrey Wolf, AB3LS

Senior Network Engineer

I'm a senior network engineer for an international public company that provides revenue cycle management, practice management, and other business services to customers in the healthcare industry. I'm part of a small and tight-knit network engineering team that supports the company's global delivery platform spanning both corporate and customer product networks. As a member of this team, I am exposed to a large range of infrastructure responsibilities. As such, I have gained extensive experience with Cisco equipment and software. I regularly work on the following platforms: Cisco ASA, Cisco ISR G2/3 Routers (IOS & IOS-XE), Cisco CSR1000v Cloud Services Routers in Amazon Web Services (AWS Transit VPC) and Microsoft Azure, Cisco Nexus/Catalyst switches in remote office access and datacenter environments, and Cisco WLC/AP wireless. I have had significant exposure to network protocol standards such as: BGP, OSPF, IPSEC, DMVPN, and the following IEEE working groups: 802.1, 802.3, and 802.11. Working knowledge of Cisco technology includes: Just about everything ASA, Cisco FlexVPN, VRF-aware NAT/Routing, Cisco Catalyst and Nexus switching, Policy Based Routing (PBR), WCCP. I also have fair exposure/understanding of additional Cisco networking products such as: Cisco Fabricpath, Cisco TACACS+ with Cisco ISE, Cisco Catalyst VSS, Cisco FirePOWER (SourceFire) IDS/IPS, and the Cisco Umbrella DNS enterprise service. On top of this hands on working knowledge of enterprise networking, I have taken a special interest in network automation and orchestration. I have used software such as Ansible to perform automated network device software upgrades and other scripted tasks. I've also used Terraform to deploy AWS cloud networking components and Transit VPCs. I am very interested in getting my hands on Cisco's new SD-WAN and DNA Center products which bring commercial grade automation natively to Cisco products. To say the least, I love networking and can quickly learn new protocols and hardware. In my spare time, I maintain my own private network, maintain cloud hosted Linux servers for personal and business hosted websites/email/DNS, talk to people all over the world with amateur (ham) radio, and travel as much as possible.
