About me
I build voice infrastructure that carries real traffic. 20+ years in open-source telephony; FreeSWITCH, Asterisk, Kamailio, SIP, WebRTC. I've deployed production systems for banks, financial institutions, and contact centers, including migrations off Avaya, Cisco, and Genesys onto open-source stacks that cost a fraction to run.
Lately I work at the edge of voice and AI: FreeSWITCH bridged to Pipecat and LiveKit agents, sub-second speech pipelines, conversational IVR that doesn't feel like an IVR.
I audit before I build. If your problem is simpler than you think, I'll tell you.
