Here is my previous projects
in the first project, I implemented GPT Response and learning with pinecone vector database using OpenAI Embeddings with langchain and built search engines by the embedding.
and second and third project, I implemented PDF uploading and reading the data and then vector store using pinecone + langchain.
And then allow users to chat with gpt based on the provided PDF data.
I can start working immediately and can work full-time in your time zone.
Thanks
