    Milestone

    You can design, deploy, and evaluate a multi-turn conversational assistant with persona-consistent responses and basic error handling.

  2. Conversational Architecture & RAG

    6 weeks
    Goals
    • Master LangChain or LlamaIndex for building RAG pipelines and agent-based architectures
    • Learn dialogue state management, conversation memory strategies, and context window optimization
    • Build and evaluate a domain-specific RAG application with proper chunking, embedding, and retrieval tuning
    Resources
    • LangChain documentation and Harrison Chase's video tutorials
    • LlamaIndex documentation and RAG optimization guides
    • Pinecone learning center on vector search fundamentals
    • DeepLearning.AI 'Building and Evaluating Advanced RAG Applications' short course
    Milestone

    You can architect a production-quality RAG system with appropriate retrieval strategies, conversation memory, and automated evaluation.

  3. Interaction Design & Evaluation

    5 weeks
    Goals
    • Learn conversational UX principles including turn design, error recovery, escalation patterns, and persona frameworks
    • Build automated evaluation harnesses combining LLM-as-judge, human preference ratings, and task-completion metrics
    • Study trust and safety patterns including hallucination mitigation, content filtering, and responsible AI guardrails
    Resources
    • Google's People + AI Guidebook (PAIR)
    • Nielsen Norman Group articles on conversational UX design
    • OpenAI Evals framework and custom evaluation methodology papers
    • Anthropic's research on Constitutional AI and helpfulness/harmlessness/honesty frameworks
    Milestone

    You can design interaction systems that are measurably effective, safe, and aligned with user expectations, backed by rigorous evaluation methodology.

  4. Production Systems & Multi-Modal Interaction

    5 weeks
    Goals
    • Learn to deploy AI interaction systems with proper monitoring, logging, drift detection, and feedback loops
    • Explore multi-modal interaction patterns combining text, voice, vision, and structured data
    • Build a portfolio project demonstrating end-to-end ownership from interaction design through production deployment
    Resources
    • AWS Bedrock or Google Vertex AI deployment documentation
    • LangSmith for production observability of LLM applications
    • Weights & Biases experiment tracking best practices
    • Conference talks from UXDX, AI Engineer Summit, and Interaction Design Foundation on AI product design
    Milestone

    You can ship, monitor, and iteratively improve a multi-modal AI interaction system in production, with robust evaluation and user feedback integration.

  5. Advanced Agent Design & Strategic Thinking

    4 weeks
    Goals
    • Design complex multi-agent orchestration systems with human-in-the-loop oversight
    • Develop frameworks for measuring ROI and business impact of AI interaction improvements
    • Build thought leadership through writing, speaking, or open-source contributions in the human-AI interaction space
    Resources
    • LangGraph documentation for stateful multi-agent workflows
    • Andrew Ng's 'Agentic Design Patterns' materials
    • Academic papers on human-AI teaming and augmented decision-making
    • Case studies from companies like Anthropic, Intercom, and Duolingo on AI interaction engineering at scale
    Milestone

    You are capable of leading human-AI interaction strategy for an organization, designing agent systems that balance autonomy with human oversight, and mentoring junior practitioners.

Practice Projects

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

Persona-Driven Customer Support Bot

Beginner

Build a multi-turn customer support chatbot for a fictional e-commerce company with a defined persona, tone guidelines, and graceful escalation to human agents when the AI is uncertain. Focus on conversation flow design, prompt architecture, and basic error handling.
