RELATED EXPERIENCE:

FS24-7 Ltd. August 2016 - Current

I am working currently as a on-call network engineer for Field Service 24/7. The company has its clients all over the wide San Francisco Bay Area and whenever there is an issue with one of the clients' network, I would get an automated email with the problem descriptions, accept the project and drive to the site to solve the issue. The issues are standard network problems, that would include troubleshooting of the network equipment such as routers, switches, load balancers, firewalls, decommission of the old equipment, RMA submittals, replacement of the failed devices and installation and configuration of the new ones using the customers' standard config policies, creation of VPN tunnels to remote offices and setting up a firewall rules, ACL's, adding new Access Points to the existing wireless LAN's, installing the equipment racks, new printers, UPS' or cabling upgrades. Also we I would sometimes the site surveys in order to help the local teams come up with the decision what need to be brought in and how much power would be required to sustain their networks. If the customer would like to decommission the old network due to a sudden growth of business, I would create a Visio diagrams with all the necessary equipment and present a new solution for a more sustainable working environment and better, efficient and more scalable networks. Worked on variety of network equipment such as Cisco Catalyst routers/switches, Nexus switches, Juniper routers/switches, F5 Load Balancers, Cisco ASA, Checkpoint and Palo Alto Networks firewalls, Cisco, Ruckus and Aruba WLAN controllers among the others.

Monitise Americas, Inc. March 2016 – July 2016

I was hired as a consultant to assist their network security/system engineer in stabilizing the existing network infrastructure, to present a topology diagram of the current state of the network or “as is” and produce a plan of a stable new or “to be” network infrastructure. The product Monitise Americas, Inc. was selling was a part software part phone app specialized in mobile banking so the customers were Banks and Credit Unions. The company was in transition of moving to a new co-location in Las Vegas and a new ISP (ViaWest) and needed the network straightened out before it could be moved with the company’s internal infrastructure. Next step was renewing Cisco SMARTNet contracts and replacing the inadequate equipment and ordering the new one, within very restraint budget. After that, I worked with the customers’ network/firewall contacts in order to build VPN tunnel with each financial institution. My job was to validate the new network, which was mainly a Cisco shop, reconfigure VLAN access, maintain change of passwords as a security precaution on guest Wireless LAN, help stabilize the infrastructure by adding a BigIP F5 load balancers and making the general working environment highly available and to work with customers’ teams on building the VPN tunnels at the new co-location. The company did not use routers due to restrained budget so Cisco ASA firewalls were acting as routers so most of the work was done on Palo Alto Networks firewalls (5050 and 5060) and Cisco ASA firewalls (5510, 5515X and 5525X).

Berkshire Hathaway Homestate Companies, Sept 2015 – Feb. 2016

The new environment design included implementation of Nexus switches 5010, 5500, 5548 and 2248TP, MPLS, VPLS as well as EIGRP dynamic protocol, DMVPN, IPSec, GRE tunnels, BigIP F5 load balancers, Cisco 3850’s L3 switches/routers, Palo Alto Networks firewalls (5050 and 5060) and Cisco ASA firewalls (5525X).
