> production voice AI, agent backends, and telephony that ships
I build real-time voice agents, multi-agent architectures, and the SIP/Asterisk infrastructure behind them, not demos. Production systems handling hundreds of calls a day, GH200-scale data pipelines, founding-engineer work at startups, and on-prem AI infrastructure for Andhra Pradesh State Police. ECE at VIT Amaravati; most of my learning happens in production.
