Message

At Syntura, I lead the design and development of an ISP core network across routing, MPLS services, internet edge, optical transport, and automation. I’ve designed and operated a multi-PoP backbone on Juniper MX and ACX platforms, and delivered new PoPs and core upgrades.

I also lead development of an internal network automation platform for configuration generation, provisioning, and compliance checking, using Python, Go, NETCONF, YANG, and Ansible. Earlier, at Eaton-Williams, I managed multi-site IT infrastructure and reduced annual IT spend by more than £30,000 through WAN redesign, VPN adoption, and supplier renegotiation.
