At University of Westminster, I led the migration of access switches from HPE Comware 5130/5140 to Aruba 6300M and implemented network configurations across five geographically distributed sites.
I deployed and managed network environments using Aruba Central, ClearPass Policy Manager, AirWave, and Palo Alto Next-Generation Firewalls. I also developed advanced access and NAT rules and configured VPN tunneling between remote and main sites.
Earlier, at Imperial College Healthcare NHS Trust and Joskos Solution, I configured enterprise network infrastructure, managed firewall and VPN issues, and supported Cisco ISE and Cisco ACI environments. At Joskos Solution, I also delivered infrastructure upgrades and data centre modernisation projects.
