About me
I build AI voice agents that survive real phone traffic — not just demos.
Over three years I built a full voice AI platform in the same class as Vapi and Retell: LiveKit, SIP/PSTN telephony, streaming STT/TTS, tool calling, RAG over vector search. Not configured one. Built one.
Beyond voice, I take ideas to shipped products — fast prototype, MVP, or full-scale system. 8+ years across fintech, crypto, SaaS, ERP and enterprise mobile.
Tell me what you're building and I'll tell you honestly what it takes.
