  1. Foundations: LLMs, Embeddings, and Basic Retrieval

    4 weeks
    Goals
    • Understand transformer architecture, tokenization, and context window mechanics at a conceptual level
    • Learn how text embeddings work and practice generating them with OpenAI and HuggingFace models
    • Build a basic semantic search engine using FAISS or ChromaDB over a small document corpus
    Resources
    • Andrej Karpathy's 'Intro to Large Language Models' video
    • HuggingFace NLP Course (free)
    • LangChain documentation: Retrieval tutorials
    • OpenAI Embeddings API guide
    Milestone

    You can embed a document set, index it in a vector store, retrieve relevant chunks, and pass them to an LLM to answer questions.

  2. RAG Pipeline Design and Evaluation

    6 weeks
    Goals
    • Build production-grade RAG pipelines using LangChain or LlamaIndex with multiple retrieval strategies
    • Implement chunking experiments (fixed-size, recursive, semantic) and measure retrieval quality
    • Learn RAGAS and DeepEval frameworks to systematically evaluate answer faithfulness and relevance
    Resources
    • LlamaIndex documentation and starter notebooks
    • LangChain RAG tutorial series
    • RAGAS documentation and GitHub examples
    • Pinecone learning center: Advanced retrieval patterns
    Milestone

    You can design a RAG pipeline end-to-end, benchmark its performance, and explain trade-offs between retrieval strategies with data.

  3. Advanced Context Strategies: Re-ranking, HyDE, and Knowledge Graphs

    5 weeks
    Goals
    • Implement hybrid search (dense + sparse) and cross-encoder re-ranking pipelines
    • Explore advanced retrieval patterns like HyDE, sentence-window, and auto-merging retrieval
    • Build a knowledge graph layer using Neo4j and integrate graph-based retrieval into RAG
    Resources
    • LlamaIndex advanced retrieval documentation
    • Cohere rerank API docs and tutorials
    • Neo4j GraphAcademy (free courses)
    • Research papers: HyDE, Self-RAG, CRAG
    Milestone

    You can architect multi-stage retrieval systems that combine vector search, re-ranking, and structured knowledge to dramatically improve answer quality.

  4. Memory, Multi-Agent Context, and Production Systems

    5 weeks
    Goals
    • Design conversation memory architectures with summarization, buffer, and hybrid strategies
    • Build multi-agent systems where agents share and pass context through LangGraph or similar frameworks
    • Learn production concerns: caching, streaming, observability, cost monitoring, and guardrails
    Resources
    • LangGraph documentation: Memory and state management
    • OpenAI Assistants API: Threads and retrieval features
    • Weights & Biases: LLMOps tracking
    • AWS Bedrock knowledge base tutorials
    Milestone

    You can build and deploy a context-aware, multi-agent AI system with persistent memory, observability, and cost controls in a production environment.

  5. Portfolio, Specialization, and Industry Application

    4 weeks
    Goals
    • Build 2-3 portfolio projects applying context engineering to real-world domains (legal, healthcare, developer tools)
    • Specialize in one advanced area: agentic context flows, domain-specific knowledge bases, or context security
    • Prepare for interviews by practicing system design for context-heavy AI applications
    Resources
    • GitHub: Open-source RAG projects to contribute to
    • Industry blogs: Anthropic, OpenAI, LangChain engineering write-ups
    • Conference talks from AI Engineer Summit and LLMs in Production
    Milestone

    You have a strong portfolio, can whiteboard context architectures for any domain, and are ready to interview for AI Context Engineering roles.

Practice Projects

Apply your skills with hands-on projects. Ordered by difficulty.

Build a Document Q&A Bot with RAG

Beginner

Build a question-answering application over a collection of PDF documents using LangChain, OpenAI embeddings, and ChromaDB. Users can upload documents and ask natural language questions, receiving answers with source citations.

~15h
Document chunkingEmbedding generationVector store indexing

Chunking Strategy Benchmark Suite

Beginner

Create a systematic benchmarking tool that tests 4-5 different chunking strategies (fixed-size, recursive, semantic, sentence-window) on a fixed document set and evaluates retrieval quality using RAGAS metrics.

~20h

Hybrid Search Engine with Re-ranking

Intermediate

Build a hybrid retrieval system combining BM25 sparse search with dense vector search, followed by a cross-encoder re-ranker. Benchmark against pure dense retrieval on a domain-specific dataset.

~30h

Knowledge Graph-Enhanced RAG Pipeline

Intermediate

Construct a knowledge graph from a document corpus using LLM-based entity and relation extraction, store it in Neo4j, and build a retrieval pipeline that combines graph-based and vector-based retrieval.

~40h
