Custom AI Chatbots with RAG (FAISS/Pinecone/Qdrant) + Backend APIs

I build custom AI chatbots using RAG (Retrieval-Augmented Generation) that answer from your documents or knowledge base. Includes backend APIs (FastAPI/Django), embeddings, vector search (FAISS/Pinecone/Qdrant), authentication, and deployment on AWS/Azure/GCP or on-prem servers behind Nginx reverse proxy.
