Pfizer Advanced: AI-Powered Document Insights & Data Extraction Externship

Prototype AI-powered document intelligence with Pfizer—using OCR, LLMs, and RAG to automate real enterprise PDF workflows and build a standout portfolio project.

AI & MLPythonDocument IntelligencePresentation Skills

Overview

The work prototyped an AI-powered document-intelligence pipeline for enterprise PDF workflows, combining optical character recognition, retrieval-augmented generation, and large language models. The project analyzed model choices and integration points, and produced a functioning prototype that demonstrated automated data extraction from sample PDFs.

Pfizer Advanced: AI-Powered Document Insights & Data Extraction Externship

What I've accomplished

I reviewed a pharmaceutical sample file, catalogued document types and date formats, and identified OCR and NLP extraction risks including table misalignment, ambiguous date fields, and domain-specific abbreviations.

Project breakdown

I reviewed a pharmaceutical sample file, catalogued document types and date formats, and identified OCR and NLP risks such as table misalignment, scanned pages, similar date-field ambiguity, and technical abbreviations that could hinder extraction.
