Prototype AI-powered document intelligence with Pfizer—using OCR, LLMs, and RAG to automate real enterprise PDF workflows and build a standout portfolio project.
The work examined how AI systems read and represent pharmaceutical documents, combining NLP, LLM concepts, and OCR techniques. The project summarized how text is converted into numerical vectors, how models are trained on corpora to predict or fill tokens, and how vectors are decoded into human-like output. The deliverable documented these mechanisms as they apply to scanned and born-digital

I produced a technical explanation showing how LLMs convert text into numerical vectors, are trained to predict or fill tokens, learn language patterns, and decode vectors back into human-like text.
I described how LLMs converted input text into numerical vectors, were trained on corpora to predict next tokens or fill gaps, learned language patterns and grammar, and decoded vectors to generate human-like output.
The externship module required Python work in Colab. I ran notebooks to create data structures, clean tabular data with pandas, parse nested JSON into dataframes, standardize text (including unicode and contractions), and apply denoising, contrast and thresholding to a scanned document. The…
