Hello, I'm
I manage complex IT infrastructures, ensuring robust system security and high availability. I deploy and monitor enterprise solutions ranging from server architectures to comprehensive backup systems.
As Furkan İkkan, I have extensive experience in network and system administration. From government institutions to private sectors, data centers to e-commerce platforms, I have provided robust infrastructure management, server configuration, and monitoring solutions.
My core focus is ensuring continuous system availability, preparing for disaster recovery scenarios, and preventing security breaches. I also place great importance on learning new tools and tracking modern methodologies in the ever-evolving world of IT operations.
