A production AI assistant that answers from your own documents, data, or policies. I design the retrieval pipeline (chunking, embeddings, re-ranking), connect it to Claude or OpenAI with tool calling, and deploy it where your team or customers already work: web chat, Slack, WhatsApp, or your app. Every answer cites its sources, and there's a clear handoff to a human. Includes: scoping and spec, document ingestion, vector database (Pinecone or pgvector), cited answers, one channel, an evaluation set to measure quality, deployment, docs, and 2 weeks of support.
