PROJECTS

AI project legal documents summarization

blueberry Global
Duration : 04-May-2026 - 25-Sep-2026

<p>I worked on an AI-powered Legal Document Summarizer that automatically analyzes legal documents and generates concise summaries. The main objective was to reduce the time required to understand lengthy legal documents.</p><p>I developed the backend using Python and FastAPI. We used Llama 2 through Ollama for document summarization and implemented a RAG pipeline to retrieve relevant information from the uploaded documents.</p><p>The document was first processed and divided into smaller chunks. We generated embeddings for these chunks and stored them in a vector database such as FAISS. When a user asks a question or requests a summary, the system retrieves the most relevant chunks and sends them as context to the LLM.</p><p>I worked on the document processing, API development, RAG workflow, prompt engineering, and integration. We also provided a React-based UI where users could upload documents, generate summaries, and download the output as a PDF.</p><p>The technologies used were Python, FastAPI, Llama 2, Ollama, RAG, embeddings, FAISS, React, SQLite, and REST APIs.</p>
