What I Built

RAG with dedicated Evaluation Framework - essential for validating system performance

Critical for unseen information - evaluation framework is especially important for data LLMs haven't encountered during training

Guarantees correctness - ensures results are accurate and reliable

Enables measurement and improvement - identifies failure points and failure rates to systematically enhance the system

The Challenge

Organizations struggle to extract insights from vast document repositories, with teams spending hours daily searching through technical documentation

Traditional keyword search misses 60% of relevant information due to semantic gaps, leading to duplicated work and missed opportunities.

RAG Results Visualization

Selecting a right approach

Imagine searching through hundreds of PDF documents to find one answer. Now imagine getting that answer in seconds, with sources cited.

Two-Stage Retrieval

Vector search + AI re-ranking for 40% better relevance

Custom Evaluation Framework

Precision, Recall, and MRR metrics for continuous improvement

Real-Time Q&A Interface

Source attribution with 3s avg response time

Production-Ready API

Modular design with scalable architecture

The Architecture

Understands what you're really asking (not just keywords), checks every relevant document instantly and brings you the best answers.

The Architecture

Smart Retrieval System

The system understands intent, not just matching words. Searching "How do I reset?" finds answers about "reinitialization" too.

Vector embeddings OpenAI + LanceDB for semantic search

Cohere re-ranking reduced false positives by 35%

Achieved 92% precision vs. 67% baseline keyword search

L2 distance metric for optimal similarity matching

Evaluation Framework

Every answer is tested and we know if it's correct or not.

Built custom metrics: Precision, Recall, Mean Reciprocal Rank (MRR)

AI-powered answer correctness validation using GPT-4

25 test questions with ground truth for continuous benchmarking

Automated test harness for model iteration and improvement

Production Architecture

Like LEGO blocks - swap out parts without rebuilding everything. Easy to improve and maintain.

Modular design: Indexer → Datastore → Retriever → Generator

CLI + Web interface built with Python/Reflex framework

Handles 60+ document chunks with sub-second retrieval

SQLAlchemy + Alembic for robust database management

Results & Impact

What used to take a team member half their morning now happens while their coffee is brewing.
