  2. Core Stack: RAG, Agents & Orchestration

    6 weeks
    Goals
    • Master Retrieval-Augmented Generation (RAG) pipelines
    • Learn agent frameworks like LangChain or LlamaIndex
    • Understand vector databases and embeddings
    Resources
    • LangChain/LlamaIndex official documentation and tutorials
    • DeepLearning.AI courses on LangChain and RAG
    • Pinecone/Weaviate vector database getting started guides
    Milestone

    You can build an AI assistant that answers questions based on a set of uploaded PDF documents, using RAG with a vector store.

  3. Personalization & Integration

    6 weeks
    Goals
    • Design systems for personal knowledge graphs
    • Implement multi-tool and multi-API agent workflows
    • Learn secure OAuth flows for third-party service integration

    • Advanced LangChain documentation on tools and custom chains
    • Project-based learning: build a personal assistant that connects to a calendar API
    Milestone

    You can build an assistant that, upon a voice command, checks your calendar, finds a relevant email, and drafts a meeting summary for you, executing multiple tools in sequence.

  4. Productionization & Advanced Topics

    4 weeks
    Goals
    • Deploy and monitor AI applications on cloud platforms
    • Implement robust evaluation and feedback loops
    • Explore advanced concepts like fine-tuning and multi-agent systems
    Resources

    • Research papers on autonomous agents and reflection patterns
    Milestone

    You can deploy a personal assistant application to a cloud platform with logging, error tracking, and a basic dashboard to monitor performance and cost.

Practice Projects

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

Second Brain AI: Personal Knowledge Q&A

Beginner

Build a CLI or simple web app that lets you 'chat' with your own collection of Markdown notes or PDF files. This solidifies core RAG skills.

~15h
Document LoadingText SplittingEmbedding Generation

Proactive Meeting Prep Assistant

Intermediate

Create an agent that, given a calendar event, automatically gathers relevant documents from your drive, recent email threads, and past meeting notes to generate a one-page briefing document.

~25h
Multi-Source Data RetrievalMulti-Tool Agent DesignSummarization

Voice-Activated Personal Assistant with Memory

Intermediate

Develop a voice interface (using Whisper & TTS) for an assistant that can remember user facts and preferences across sessions, storing them in a structured knowledge graph or database.

~30h
Speech-to-Text IntegrationLong-Term Memory ArchitectureState Management

Autonomous Research Agent

Advanced

Build an agent that can take a high-level research question (e.g., 'What are the latest trends in sustainable packaging?'), break it into sub-tasks, search the web, synthesize findings, and produce a structured report with citations.

~40h
