Skills

Like many others, I started learning and working as a Network Engineer about 13 years ago, and have valuable experiences with both IGP and BGP routing and Traditional switching in LAN, WAN, and Data Center. But I've been focusing on Data Center for the past 5 years. After studying a lot and gaining many experiences with both single-site and multi-site environments, I've become a Data Center Solution Architect relying on Traditional technologies, Software-defined Data Centers (SD-DC), and also Codified or Automated infrastructures using Ansible and Python. (Basically, I was a C++ and VB programmer before I migrated to the Network engineering world!)
---
I'm really interested in Cisco's SDN solutions for Data Center, Including ACI and HyperFlex, thus I have studied a lot about them.
I've extensive hands-on Experience as an Executive Consultant and Instructor with Cisco ACI and Its integration with Firewalls, Load balancers, VMware vCenter, and OpenShift as well. (I've taken a Kubernetes course for that.)
---
I also have hands-on Experience with Ansible and YAML Scripting. (Substantially in Data Center Interconnection)
I've hands-on Experience with Juniper SRX 5800 firewalls and have got through JNCIS-Sec and JNCIP-Sec courses.
I also have an LPIC-1 level of knowledge about Linux.
