Hello there, I am a JNCIA professional and network expert having more than 12 years’ experience of working with multiple organizations like Banks, ISP and vendor partners. Following are the benchmarks I have which might be helpful for employer to get an overview and choose me to serve their requirement. ✅ I have certification of JNCIA-Junos from Juniper, I also worked a lot configuring and installing Cisco, Extreme and Huawei routers and swithes. ✅ I also have good knowledge of network automation using Python and Ansible. ✅ During my job period I mostly worked to design and deploy network & security infrastructure of several companies. But now I manage a team of networking engineers delivering projects over Americas. ✅ I have good knowledge and experience of working on devices of multiple OEM like Cisco, Juniper, Huawei, Extreme etc. ✅ I always document every project, so when you further have a problem on your network you will be able to see all the details to help to solve the issue. I will be glad if the above mentioned criteria makes you realize that I am able to meet your requirement then would like to request to have a brief discussion on your project and requirements first after that award me with the work order. I always try to keep my words given to employer and I believe it helps me a lot to deliver my work on time. Thanks with best regards, Eliu Hahner
