You will get production-ready RAG system with LangChain, LlamaIndex & OpenAI
Project details
Build a custom RAG system using LangChain, LlamaIndex, OpenAI GPT-4, and modern vector database architecture. I develop scalable AI solutions for enterprise knowledge bases, AI chatbots, document intelligence, and SaaS applications with accurate, context-aware responses.
This service focuses on production-grade RAG pipelines that improve response accuracy, reduce hallucinations, and enable intelligent search over PDFs, documents, APIs, and business data. The system is optimized for scalability, performance, and real-world deployment.
Whether you need an AI chatbot, AI search engine, knowledge assistant, or AI SaaS backend — I deliver complete end-to-end implementation from design to deployment.
✅ Custom RAG system development
✅ LangChain, LlamaIndex & OpenAI integration
✅ GPT-4 powered AI applications
✅ Semantic search & embeddings
✅ Vector databases (Pinecone, Qdrant, FAISS)
✅ Hybrid search (BM25 + vector search)
✅ Document processing (PDF, DOCX, APIs)
✅ Context memory & retrieval optimization
✅ Source-grounded AI responses
✅ Hallucination reduction techniques
✅ FastAPI backend & scalable APIs
✅ AI agents & workflow integration
✅ Docker, AWS & cloud deployment
