Enhanced RAG Model Development

I'm seeking a skilled professional to enhance the RAG model to process uploaded files more effectively, with a focus on organizational specificity.

Key Requirements:
- The model should be able to handle and process all file types, including text files, PDFs, and CSVs.
- The interaction with the files should be improved to ensure efficient processing.
- The model should keep versions of the files instead of overwriting or appending data.

Ideal Skills:
- Proficiency in machine learning and model enhancement.
- Experience with RAG models.
- Familiarity with various file types and their processing.
