I will integrate OpenAI and AI features into your existing web application

I build and integrate AI powered features into production web applications using OpenAI and LangChain. Whether you need a simple chatbot, text generation, content summarisation, or a full RAG pipeline that answers questions from your own documents, I have shipped all of these in real production environments. You get OpenAI API setup, custom prompt engineering, streaming responses, conversation history, token cost controls, secure API key handling, and full source code delivery.
