I will develop custom rag chatbots and ai agents using langchain


About this gig
Need an intelligent AI chatbot that actually understands your private data without hallucinating?
I specialize in building production-ready Retrieval-Augmented Generation (RAG) chatbots, custom LLM pipelines, and AI agents that turn your documents, databases, or APIs into actionable knowledge bases.
What I Offer:
Production RAG Chatbots: Connected to your PDFs, text files, SQL databases, or Notion spaces.
Advanced AI Frameworks: Built using LangChain, LlamaIndex, and Ollama for local or cloud setups.
Model Integrations: Seamless integration with OpenAI, Gemini, Claude, or open-source models like DeepSeek.
Specialized AI Agents: Chatbots optimized for specific domains, including medical informatics or enterprise technical data.
Key Features Included:
Vector Database Setup (Pinecone, ChromaDB, FAISS)
Optimized semantic search & chunking strategies to minimize API costs
Clean, conversational UI or lightweight API endpoints (FastAPI/Flask)
Secure user data handling
Why work with me? I am an AI Engineer focused on building scalable, memory-efficient AI systems. I don't just plug in basic APIs; I optimize retrieval strategies for accuracy.
Please message.
