    • Python async programming course (Real Python or FastAPI docs)
    • OpenAI API documentation and cookbook examples
    • Anthropic Claude API quickstart and prompt engineering guide
    • Simon Willison's LLM tooling blog posts
    Milestone

    You can build a simple chatbot that calls an LLM API, handles streaming responses, and manages conversation history

  2. Prompt Engineering and RAG Fundamentals

    6 weeks
    Goals
    • Master advanced prompt engineering techniques including few-shot, chain-of-thought, and structured output parsing
    • Understand embedding models, vector similarity search, and basic RAG pipeline architecture
    • Build a working RAG application with document ingestion, embedding, retrieval, and generation
    Resources
    • LangChain documentation and tutorial series
    • DeepLearning.AI short courses on RAG and LangChain
    • OpenAI embeddings and vector search guides
    • LlamaIndex documentation for RAG patterns
    Milestone

  3. Agent Design and Workflow Orchestration

    6 weeks
    Goals
    • Design multi-step agent architectures with tool calling, planning, and error recovery
    • Learn workflow orchestration patterns using LangGraph, Temporal, or Prefect
    • Implement memory systems including short-term conversational memory and long-term vector-stored memory
    Resources
    • LangGraph documentation and multi-agent tutorials
    • Temporal.io getting started guide
    • CrewAI framework documentation
    • Harrison Chase's talks on AI agent architectures

  4. Production Deployment and Observability

    5 weeks
    Goals
    • Deploy AI workflows as containerized microservices with proper scaling, health checks, and graceful degradation
    • Implement comprehensive observability including LLM-specific metrics, cost tracking, and output quality monitoring
    • Build evaluation pipelines with automated scoring, regression detection, and A/B testing
    Resources
    • Docker and Kubernetes fundamentals
    • Langfuse or Helicone for LLM observability
    • GitHub Actions CI/CD tutorials
    • AWS Bedrock or GCP Vertex AI deployment guides
    Milestone

    • Open-source contribution guides for LangChain, LlamaIndex, or similar projects
    • Conference talks from AI Engineer Summit and similar events
    Milestone

    You can architect enterprise-grade AI workflow systems, lead technical design reviews, and mentor junior engineers

Practice Projects

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

Intelligent Document Q&A Bot

Beginner

Build a web application that ingests PDF and text documents, indexes them using embeddings and a vector store, and allows users to ask natural language questions with cited answers. Focus on clean chunking, effective retrieval, and accurate generation.

~25h
RAG pipeline designVector database managementPrompt engineering

Multi-Tool Research Agent

Intermediate

Create an AI agent using LangGraph that can search the web, query a database, read documents, and synthesize findings into a structured report. Implement error handling, observability, and a human review checkpoint before final output.

~40h
Agent architectureTool integrationWorkflow orchestration

Customer Support Automation Pipeline

Intermediate

Build a production-grade customer support workflow that classifies incoming tickets, retrieves relevant knowledge base articles, drafts responses using RAG, and routes complex cases to human agents with context. Include evaluation metrics and cost tracking.

~50h
RAG optimizationClassification and routingProduction deployment

Multi-Model Router with Fallback Chains

Advanced

Design and implement a system that automatically routes requests to different LLMs (GPT-4o, Claude, Llama) based on task complexity, cost constraints, and latency requirements. Include fallback chains, caching, and A/B testing infrastructure.

~60h
Model routingCost optimizationCaching strategies

Real-Time RAG Ingestion Pipeline

Advanced

Build an event-driven ingestion system that processes incoming documents (PDFs, web pages, emails) in real-time, chunks and embeds them, updates the vector store, and makes them immediately available for retrieval. Include monitoring, error recovery, and document versioning.
