Gabriel Benjamin

Responsible for configuring small to medium LAN environments. Most infrastructure environments consisted of Cisco systems technologies. Duties include, setting up more efficient routing and advanced technology concepts such as MPLS, EIGRP, and Dmvpn; switching concepts such as setting up Vlans, STP, and VLSM; as well as security practices for servers, switches, and routers alike. Skill set also includes tcp/ip, port addressing, and subnetting; specifically finding better subnets so that address space is used in the most effective way utilizing both IPv4/IPv6. I work frequently with CUCM (Cisco Unified Call Manager) more specifically the configuration of voice gateways, IP phones, Cisco collaboration applications such as Cisco Spark and Jabber/Webex, LDAP and active directory integration and performance Qos meeting IP SLA’s. I am Familiar with T1 PRI circuits and how they incorporate into a Voice environment. I am able to demonstrate excellent cable management and LAN closet cleanup. I am familiar with wireless networks, Cisco 2500/5500/9800 series controllers, and AP’s/Airtight as well as 802.11/802.1x schemes. In many of these scenario’s, the configurations were completed in a virtual or remote environment which has increased my familiarity with virtual and hosting software such as VMware, Hyper-V, PuTTY connection manager, and Cisco CLI analyzer. In addition to the configuration aspect, I have worked with several network monitoring softwares such as Solarwinds, Cisco prime, and Netbrain some which I have installed personally and incorporated into an enterprise network. With that, I have applied Tacacs, ACS server, ISE server configs to provide user and server access to network devices along with the necessary ACL’s and Nat translations needed to allow access. I am very security saavy and have used tactics such as Hardening and hardening guidelines in order to assist in combating malicious cyberattacks. Tasked with creating detailed documentation including rack diagrams, physical/logical Visio diagrams. I have also used packet tracer software like Wireshark/Dynamips to identify network and call latency. I have experience implementing application firewall access rules and object zones mostly using Cisco ASA 5500 series and ASDM GUI manager. Along with ASDM GUI, I have utilized Cisco ACI (application centric networking) and SDN (software defined networking) as the future moves towards more graphic and virtual networking. I have worked with F5 Big IP load balance networks, round robin one arm and two arm configurations, Pool, Node, and VIP interface creation. Along with that I was able to become efficient working with DNS/DHCP configuration using Infoblox/BlueCat. Worked with industry professionals such as Presidio, Netcraftsmen, and CDW on various intensive network development projects. Worked with systems/cloud engineers to migrate CISA gateway and on-prem network into AWS hosted GovCloud.
