About

In 2025, I wrapped up nearly five years as a DNS Engineer at Nominet, where I helped operate the core infrastructure behind the .UK namespace, the NHS, and global TLDs. Alongside this, I built tooling like nominet-exabgp-healthcheck, contributed to open-source projects such as Oxidized and ESPHome, and created containerised services from PowerDNS to Factorio MapShot. I’m passionate about internet infrastructure, automation, and building systems at every scale — from critical production DNS to hobby projects just for fun.

Work Experience

N

Nominet

Oct 2020 - Jul 2025
DNS Engineer
Engineered and operated the core DNS infrastructure underpinning the .UK namespace, the NHS, and numerous global TLDs including .ieee, .office, and .skype. Built 'nominet-exabgp-healthcheck', a modular Python health-checking tool integrated with ExaBGP to enable self-healing BGP failover. Led TLD migrations such as gov.uk, authored technical runbooks for onboarding registries, and was the first engineer in Nominet’s dedicated DNS team after the split from Networks. Worked with BIND, PowerDNS, NSD, and Unbound, and drove automation initiatives using Python, Ansible, and containerised tooling.
B

Boundless Networks

August 2016 - Oct 2020
Senior Network & Systems Engineer
Architected and maintained service provider infrastructure across core, distribution, and access networks, using BGP, MPLS, and OSPF on multi-vendor platforms (Juniper, Mikrotik, Ubiquiti, Cambium). Automated configuration management with Oxidized/Git and Ansible, and integrated NetBox for live system documentation. Designed and supported Linux-based infrastructure stacks including DNS servers, RADIUS, SQL databases, and virtualisation platforms (Xen/KVM). Delivered large-scale networking projects from wireless backhaul to enterprise campus deployments, and managed VoIP services and PBX systems for customers. Mentored junior engineers and acted as an escalation point for operational incidents.
