I'm a computer engineer ( Hardware) from Iran; it's a long time since I worked in the telecommunication field and working as a project manager, CFO, and CEO in different international Companies; I was away from the technical field ( working directly with routers and servers ) for couple years and decided to start rebuilding myself as I had moved from Iran to the US. I'm a famous manager here, OTO. Unfortunately, I found my certificates are worthless in the US. I found Nexgent, and right now, I'm thrilled to see Jacob Hess; he is a great mentor, and I found him a great teacher.
