About Me

With nearly 30 years experience in all aspects of IT, I've come to specialise in server and network administration with a strong DevSecOps focus on automation and stability.


I’ve run global networks spanning 200+ locations, worked extensively with Juniper, Cisco, HP products to build, secure and maintain corporate networks and VPNs, and built tools to reduce outages and simplify management. If you need someone who can both fix problems and prevent them, I can help.
