Hi, I am Abdul Kader Linkon, BSC in computer science and engineering. I completed my CCNA and CEH in 2011 and 2018. Now I am in Liberia as a Technical Manager post at a WISP since 2020. I worked on Timor Leste before as a Network Engineer at a Mobile operator. I was a Core Network Engineer position (grade of senior executive officer) at an Insurance Company in Bangladesh from 2013 to 2018. I can help you if you are an FTTH / ISP / WISP / Enterprise / Hotspot service Provider. I can ensure your network & DATA centre security also. If you want a Network Monitoring solution then you can see my presentation: https://www.youtube.com/watch?v=3Bm-BgVCAqE&t=239s
