Hi,
For the network infrastructure I would be of a great help. As for the linux servers, not that much, besides that I can do initial installations, configure some settings like network, DNS, iptables etc.
I have experience in networking, wireless, network security, virtualization and Microsoft Windows Server technologies. I currently work in international company, with offices scattered around the globe and around 5000 employees. I am a network engineer with 10 years experience, where I have designed, implemented and configured various networks, including switches, routers, firewalls, UTM devices, wireless controllers and access points, virtualized and Microsoft infrastructure. From the vendors, I have experience with Cisco (Catalyst, routers, ASA, Aironet), Juniper (JunOS and former Trapeze wireless platform), Watchguard & Fortinet & Sophos (firewalls, VPN and UTM), VMWare virtualization, Microsoft Windows server 2008/2012/2016 (DHCP, AD, DNS, Group policies etc.)
I also have experience in VoIP, mainly with Asterisk PBX (hence my knowledge for Linux)
Regards,
Deniz
