The Domain-Specific RAG System is a generative AI project that combines Chunking strategy and Retrieval layer, built with LangChain / LlamaIndex. The project follows a clean, modular pipeline where input handling, generation, and presentation stay separated, making it easy to test, extend, and present. It showcases modern generative AI techniques while producing a working, demo-ready application.
Traditional solutions to this problem are slow, static, and unable to generate new, context-aware content on demand. Without a generative AI approach built on Retrieval layer and LangChain / LlamaIndex, users cannot get personalized, high-quality outputs quickly, and there is no straightforward way to refine or evaluate the results.
This project applies generative AI through Chunking strategy, orchestrated with LangChain / LlamaIndex and Retrieval layer. The pipeline is designed for quality and control, with validation, evaluation, and a clean interface. It generates consistent, context-aware results and can be adapted to related tasks with minimal changes.

Modular pipeline around Chunking strategy and Retrieval layer
Configurable generation and evaluation settings
Clear logging, retries, and cost tracking
Clean interface for results
Reusable components for related tasks
Evaluation of output quality
The project is layered: the input layer prepares and validates inputs through Chunking strategy; the generation layer invokes the model with LangChain / LlamaIndex and Retrieval layer; and the output layer formats and presents results via Citation and evaluation module. Shared configuration, logging, and evaluation modules support all layers, keeping the system robust and easy to extend.
