I am a Cisco and Microsoft Certified Network Engineer and I have 11 years of experience in designing, implementing, and providing operations support for medium and large enterprise networks. I have experience in working on Cisco routers and switches, Juniper/Cisco/Palo Alto firewalls, F5 load balancers, Riverbed WAN Optimizers, and Cisco/Aruba wireless controllers and Access points. I design network and security infrastructure which can scale, has high availability, and can proactively detect and resolve issues to maintain network uptime of 99.9% and to deliver uninterrupted business continuity. I can also help you identify other OEM hardware for your business requirement, something with zero touch provisioning, high ROI, low initial capital, but is reliable in terms of hardware and software. I can also help you troubleshoot network and infrastructure issues in a multi vendor environment, which interoperates with storage, systems, and servers. Talk to me in order for me to quote a custom gig for your business based on the number of devices in your network.
