Practice Projects
Apply your skills with hands-on projects. Ordered by difficulty.
Document Q&A Bot with Hybrid RAG
BeginnerBuild a question-answering system over a PDF knowledge base using LlamaIndex or LangChain with vector retrieval, BM25 fallback, and source citation. Compare retrieval strategies and evaluate answer quality.
Knowledge Graph-Powered Grounding System
IntermediateDesign a Neo4j knowledge graph for a specific domain (e.g., Wikipedia biographies), populate it from unstructured text using NER and relation extraction, then build a GraphRAG pipeline that answers questions using graph traversal.
Self-RAG with Reflection and Correction
AdvancedImplement a self-correcting RAG system using LangGraph where the system grades retrieval relevance, decides whether to re-retrieve or reformulate queries, and generates critique tokens to evaluate its own faithfulness before producing a final answer.
Real-Time Knowledge Ingestion Pipeline
IntermediateBuild a pipeline that ingests news articles or RSS feeds in real-time, extracts entities and key facts, updates a vector index, and makes new knowledge immediately available to a RAG-based assistant - with staleness detection for outdated entries.
RAG Evaluation Framework with CI/CD Integration
IntermediateBuild a comprehensive evaluation harness using Ragas and DeepEval that tests a RAG pipeline against a golden dataset of 200+ questions, generates quality reports, and blocks deployment if faithfulness or relevance scores drop below thresholds.
Domain-Specific Embedding Fine-Tuning
AdvancedFine-tune a sentence-transformer model on a specialized corpus (e.g., legal contracts or medical literature) using contrastive learning. Build an evaluation pipeline comparing the fine-tuned model against general-purpose embeddings on domain retrieval tasks.
