PROFESSIONAL EXPERIENCE:

Confidential, Bellevue, WA

Network Engineer

Responsibilities:

• As part of Uprising Networking Team in Confidential I have worked on 200+ projects for Checkpoint Firewall, Load balancers (F5,A10), Server installations, Routing and switching etc.
• Primarily worked on Installed, configured and set security policies on Cisco and checkpoint firewalls, VPN and A10,F10 products & technology ( GTM, LTM, SSL offloading, etc.).
• Worked on Firewall rules in Checkpoint R77 giving connection between different servers namely HP, Sentry appliances, Domain Controllers, San devices, Tibco which are located at different datacenters Polaris, Titan, Orion, Nexus, EIT etc .
• For public ip’s I used to write NAT rules for the traffic to pass through between internal and external ip.
• Once implemented I will be check rules and get the confirmation from customers.
• If customers have any connectivity problems between source and destination I will do troubleshoot on that particular flow using Checkpoint R77
• Worked on several A10, F5 load balancers as requests provided by different customers to implement.
• MOP’s are used to perform the requested work for different applications. I used to check the particular requested partitions. If not available it will be created. Then will proceed with creating pool members, service groups, virtual servers, snatpool etc.
• Once the mop has been implemented I will log into those LB’s to verify the devices are configured properly and if possible get the confirmation from customers too.
• I have worked on following tools/devices NSC, NMNET, HPNA, Granite, Check point, switches during my tenure.
• Worked on several few Hardware installation project updating granites, cable testing and port turn ups and validation
• On these projects I worked on following tools NEMAT, WebXng, IP Control, Granite, Technology Change and PIER for creating work orders, reverse tool, port validation etc.
• In these projects work is on configuring several types of layer2/Layer 3 switches such as Nexus3k, N5K, N7K, Cisco4000 and 6000 series.
• Primarily these projects focus on different server’s installation in the data centers. We need to find the appropriate location for them to be racked and cabled/ connected to switches.
• Once connected we will do cable testing by creating a work order for HPNA. Once it’s done we will proceed with port turn up and validation.
• Working environment is competitive and has lot of opportunity to improve my skills.
