I design, deploy and manage enterprise IT infrastructure — servers, firewalls, and networks. This is where I document real-world problems, solutions and everything I learn along the way.
Systems Administrator with 5+ years of enterprise IT experience.
Hi, I'm Okan Kaipoğlu — a Systems Administrator and Network & Infrastructure Engineer with over 5 years of hands-on experience building and managing enterprise IT environments.
My day-to-day work involves managing enterprise firewall systems such as FortiGate and Sophos, designing and maintaining switching and routing infrastructure, and administering both Linux and Windows Server environments.
I work extensively with Cisco and TP-Link routers and switches, configure VLANs, set up VPN tunnels, and handle Active Directory, DNS and DHCP services for corporate networks.
On this blog I document real problems I encounter in the field — with step-by-step solutions, CLI commands and practical notes. No filler, just things that actually work.
Roles I've held throughout my career.
