Description

I help founders, CTOs, and engineering teams design, stabilise, and scale carrier-grade VoIP, WebRTC, CPaaS, SBC, and contact-centre platforms when downtime, routing errors, or the wrong vendor decision becomes expensive.

Over 25+ years, I’ve built and repaired real-time communication systems across carrier interconnects, SIP routing, browser calling, class 4/5 voice platforms, billing, fraud controls, and cloud-native backends. Recent work includes a CPaaS platform serving 1M+ users with 99.97% uptime and 100M+ daily messages, plus a B2B voice and contact-centre platform supporting 10,000+ agent seats and 5M+ call minutes per month. I’ve also reduced bandwidth or routing costs by 30–35% and helped prevent $200K–$500K+ annual revenue loss through better platform design, routing, and fraud controls.

Clients bring me in for fractional CTO support, VoIP/SIP architecture audits, WebRTC scaling issues, SBC and carrier interconnect design, Twilio/Vonage replacement, contact-centre recovery, build-vs-buy decisions, and vendor due diligence.

If your platform is unstable, too expensive, hard to scale, or heading toward the wrong architecture, I bring specialist judgment that reduces risk and shortens time to a sound technical decision.
