I build AI agents, RAG systems, and real-time voice assistants that help businesses automate support, qualify leads, answer internal knowledge questions, and streamline operations. I’m a Senior AI Engineer with 6+ years of experience building production-grade AI systems using LangGraph, OpenAI, Claude, Pinecone, FastAPI, and custom tool integrations. My work includes enterprise chatbots, voice AI systems, knowledge assistants, and multi-agent workflows built for real usage — not fragile demos. I can help you with: • AI agents with tool calling, memory, and workflow automation • RAG chatbots over PDFs, websites, databases, and internal docs • Voice AI assistants using OpenAI Realtime, Deepgram, ElevenLabs, LiveKit, and Twilio • Python / FastAPI backends and API integrations for AI products • LLM integrations across OpenAI, Claude, Gemini, and open-source models Selected outcomes: • Multi-agent legislative drafting platform with 83% faster turnaround and 95%+ compliance accuracy • Real-time voice IVR agent with CRM integration and sub-900ms response latency • Enterprise AI sales and support assistants for lead qualification and appointment booking • AI assistants with live integrations serving 100+ users I communicate clearly, document the work well, and deliver production-ready systems with clean handoff. If you need serious AI implementation in agents, RAG, or voice AI, I can help.
