Talk to My Document: A Serverless RAG approach using Huggingface, Amazon Lex and Amazon DynamoDB

In this Post I demonstrate a RAG approach using Amazon Lex and DynamoDB and Hugging Face llm. This approach enables the use of a Lex bot and LLM to answer questions based on knowledge context from a document. This approach uses LlamaIndex for the whole RAG pipeline.
I have uploaded the whole code for the solution to Gumroad if anyone is interested to follow this.
