About Vishal P.

As a Network Security Engineer at MIO Partners, Inc, I leverage my CCNA certification and extensive experience in network configuration and troubleshooting to ensure the security and reliability of our network infrastructure. I have successfully deployed and managed essential network services such as DNS, DHCP, and IIS, and set up wireless routers to distribute internet connectivity across the network. I also troubleshoot connection difficulties and optimize network performance using my understanding of OSI layers and TCP/IP protocol. Previously, I worked as a Network Engineer at Promize IT Services Private Limited, where I identified and rectified issues in both LAN and WAN networks, installed and configured networking devices, and delivered first-line technical support for network-related concerns. I am passionate about staying updated with the latest technologies and trends in the field of computer science, and I am currently pursuing a Master\'s degree in Computer Science at Rowan University.
