I'm a Computer Science & Engineering (CSE) student in my final semester, focused on building a professional career in Network Engineering, Network Support, and Cybersecurity.

My primary networking strength is MikroTik configuration, along with practical knowledge of Cisco networking, CCNA-level concepts, routing, switching, subnetting, VLAN, firewall, VPN, network troubleshooting, Linux, network security, and Python-based network automation.

I believe in learning through hands-on labs, real-world scenarios, troubleshooting, documentation, and continuous practice.

My goal is to start my professional career as a:

• Junior Network Support Engineer
• Junior Network Engineer
• Network Security Engineer

I am continuously developing my skills in network infrastructure, network security, system administration, troubleshooting, and automation to become a well-rounded Network & Cybersecurity professional.
