I am an experienced IT professional with a strong foundation in network infrastructure design, firewall and VPN configuration, and security operations. I specialize in configuring and maintaining LAN/WAN networks, firewalls (Cisco ASA, H3C SecPath, Fortinet), and VPNs, with a focus on threat detection, prevention, and incident response using tools like Wazuh and Graylog. My expertise extends to securing cloud platforms (AWS, Zstack) and virtual environments (VMware, Hyper-V). I’m also proficient in system maintenance, technical troubleshooting, and user support across various platforms, ensuring reliable and secure IT environments.
