I am a passionate IT professional with over 3+ years of experience in networking. I have good knowledge of routing and switching, including protocols like OSPF, BGP, VLAN, and TCP/IP. I enjoy troubleshooting network issues and ensuring smooth connectivity. I am a quick learner, a team player, and always eager to improve my skills. I am looking for an opportunity to grow as a Network Engineer and contribute to maintaining a stable and efficient network environment.
