    Bangladesh - Last active: 09/04/2012 - Tests: 5

    I have over 10 (ten) years’ experience in design, build/implement and maintain computer networks of sizes varies from hundreds to thousands. My last project had Cisco routers, switches, firewalls and also IPT systems that serves nearly 2,000 (two thousand) users. My familiarity with routable protocol i.e. IP and routing protocols like RIP, EIGRP, OSPF, BGP help me to accomplish this. My Deployment experience of Call Manager 7.x and 8.x with Voice Mail (Unity Connection) and IVR makes me an excellent candidate for any small or large scale Cisco IP Telephony (IPT) System integration. I have also worked with Cisco ASA 5510, 5540 firewalls for large enterprise networks. Last but not least I have experience with networking using Microsoft Windows 200x Servers and Linux Servers, i.e. RedHat, CentOS etc. I am confident that I can deliver your network related jobs in efficient and cost-effective manner.
