I build production AI systems: voice agents that handle real phone calls, LLM and RAG applications, and the backend infrastructure that keeps them reliable at scale. Over 10+ years I've helped 25+ startups go from idea to shipped product, as both a technical lead and a hands-on engineer. WHAT I DO BEST Voice AI agents: inbound and outbound phone agents with real-time speech (Deepgram, Whisper, ElevenLabs, Gemini Live), telephony (Twilio, Telnyx, Vonage, FreeSWITCH, Asterisk, SIP/WebRTC), warm transfers, DTMF, function calling, and CRM integrations. - VoicePilot (my agency's voice agent platform): cut average response latency from 1.5s to under 800ms. - Commercial trucking company: moved their browser-based Twilio call center to AI, with smoother agent handovers that reduced operating costs and improved efficiency. - Currently: building the AI calling system for GetVocal, including SIP trunking, FreeSWITCH call handling, warm transfers to human agents, latency improvements, and end-to-end agentic calling workflows. LLM and RAG systems: chatbots, AI agents, and workflow automation using OpenAI, Claude, LangChain, and vector databases, built to be accurate, cost-efficient, and production-ready rather than demo-ready. - Oppy: SMS appointment-booking agent using RAG, tool calling, and conversational graphs, plus messaging compliance and automated A2P 10DLC approval. Backend and SaaS platforms: scalable APIs and products in Python (FastAPI, Django, Flask) and Ruby on Rails, with PostgreSQL, Redis, and React/Next.js frontends. I've built for e-commerce analytics, edtech, insurance, healthcare, and HR. Infrastructure and data: AWS and GCP, Docker and Kubernetes, CI/CD, monitoring, and data pipelines with BigQuery and Snowflake. WHY CLIENTS WORK WITH ME I own the whole system, not just one layer. A voice agent is only as good as its telephony, backend, and monitoring, and I build all of them. I've worked across healthcare, fintech, real estate, hospitality, trucking, adtech, and sales and support, so I pick up new domains quickly and ask the right questions early. If you're building an AI product or need a technical lead to get a complex system over the line, send me a message with what you're working on.
