personal profile

I have spent 15 years designing and running voice networks, mostly on Asterisk, OpenSIPS/Kamailio and Linux. That covers building and customising the PBX, running SIP proxies at scale, the carrier interconnects behind them, and the full-stack PHP that ties it all to a business. I have led and managed engineering teams alongside the hands-on work, and I hold a BSc in Computer Forensics and Security from Manchester Metropolitan University, which is where the security and compliance side comes from. I am looking for work where the voice platform is the product rather than an afterthought.
