Hi everyone, I'm a Senior AI/ML & Full-Stack Engineer with 8+ years of experience. I build real-time Voice AI agents and LLM-powered tools. Recent work includes voice agents on LiveKit, Vapi, Retell AI and Twilio that cut manual call handling by 60% in production, and RAG search systems that make AI answers more grounded and accurate. Daily stack: Python, FastAPI, Node.js, OpenAI, LangChain, Deepgram, ElevenLabs, Pinecone, AWS, GCP. Industries: healthcare, education, fintech, e-commerce, mobility, SaaS, and enterprise automation. If you're working on anything with AI - voice agents, chatbots, RAG search, automation - feel free to say hi. Happy to chat or help.
