Network Engineer

Re-architected core data centre network using Cisco Nexus 9300/9500 switches in VDC configuration for scalable design.

Built HSRP-based redundancy and vPC uplinks between access/distribution layers to eliminate single points of failure.

Migrated legacy flat VLANs to segment-based topology aligned with PCI DSS zone isolation and compliance.

Created and enforced access control policies using Palo Alto firewalls, Fortinet NGFWs, and Cisco ACLs.

Deployed and fine-tuned SNMPv3 monitoring and PRTG alert profiles for link state, CPU, memory, and interface errors.

Worked closely with app teams to identify north-south and east-west traffic flows and apply firewall rules accordingly.

Configured and audited 802.1X port-based authentication for critical user VLANs using Cisco ISE and RADIUS.

Led site surveys and designed wireless coverage maps using Ekahau for high-density Wi-Fi in industrial zones.

Integrated Wi-Fi controllers (WLC 5508/8510) with centralized AAA and dynamic VLAN assignments.

Captured and analysed real-time traffic flows with Wireshark to identify packet loss, jitter, and retransmission.

Used NetFlow data to baseline normal usage patterns and detect anomalies or excessive broadcast/multicast traffic.
