At IGLU, I design, implement and support enterprise network infrastructure across corporate offices, cloud platforms and remote access environments. I lead the Zero Trust programme, manage firewall and VPN services, and act as the senior escalation point for complex network and security incidents.

I've delivered resilient LAN, WAN, WLAN, SD-WAN and AWS connectivity, including firewall migrations, network refreshes and secure cloud integration. I also lead vulnerability management, coordinate penetration-test remediation, produce technical designs, and mentor junior engineers.
