NET_INFRA & SYS_ADMIN
Welcome to my digital space! I am Sely Nur Fauziah, a student majoring in Computer Network and Telecommunications Engineering (TJKT) at SMKN 4 Bogor, with a deep interest in network infrastructure and telecommunications technology.
My daily activities revolve around network design and management—ranging from IP address allocation (subnetting) and router/switch configuration to physical installations like network cabling. I am always enthusiastic about exploring how the internet works behind the scenes, testing various system configurations, and building network connections that are stable, secure, and efficient.
