Summary

Hello,

I have been providing integrator-based support in the field of network and security for 8 years. To summarize:

I have provided L1-L7 network and application infrastructure topology creation and architectural support services to many official and private institutions both globally and in our country.

In routing and switching, the L2-L3 vendors I have worked with include:

  • Cisco
  • Arista
  • Huawei
  • Mellanox
  • Fortinet
  • Sophos
  • Palo Alto

For these brands, I have also configured UTM setups and necessary routing protocols (BGP, OSPF).

I am capable of taking the necessary configuration actions by deploying cabling diagrams, routers (if needed), switches, and firewalls in a way that fits the topology architecture from scratch.

Currently, I am working as a Senior Network Security Engineer at a cloud service provider, where I actively use all these products (protocols). Additionally, I manage internal teams responsible for virtualization, backup, operations, storage, reporting, and system and data monitoring.
