At Nex-Tech Communication, I engineer and support multi-site enterprise LAN/WAN infrastructure. I’ve deployed Cisco SD-WAN Viptela overlays and tuned path selection, traffic steering, and failover across MPLS, broadband, and LTE circuits.
I also administer Cisco Catalyst and Nexus switches, and manage F5 BIG-IP and Citrix NetScaler traffic management. Using SolarWinds, PRTG, NetFlow, and ThousandEyes, I monitor performance and investigate network issues.
I automate network changes and validations with Python, Ansible, and Cisco DNA Center templates. I also use Wireshark to isolate packet-level problems and maintain network diagrams and documentation.
Previously, at Creative Newtech Ltd, I administered perimeter firewalls and configured VPN access. I implemented Cisco ISE 802.1X and monitored security events in Splunk, QRadar, and FireEye, while supporting HIPAA, PCI DSS, and GDPR audits.
