I build the systems that carry people's voices: phone lines, PBX, contact centres, and the IT that keeps a business running underneath them.

What I work on

Most of my work is about one thing: a call that connects the first time, and a system a team can trust every day.

VoIP
Business calling over the internet, set up for clear voice, sensible routing and a lower monthly bill.
PBX
Asterisk and FreeSWITCH systems for call routing, voicemail and conferences, built to grow with the business.
Contact centres
Custom call centre setups, designed around how your agents and your customers actually talk.
IT consulting
Networks, firewalls, servers and hardware, planned so the technology stays out of the way.
Software
Web applications and CRM integrations that connect the phone system to the rest of the business.
Data and AI
From first analysis to working models, so decisions come from your own data.
