  1. LLM Foundations & API Mastery

    4 weeks
    Goals
    • Understand transformer architecture, tokenization, context windows, and temperature/top-p at a practical level
    • Master the OpenAI and Anthropic APIs including chat completions, streaming, function calling, and system prompts
    • Build a basic conversational copilot that handles multi-turn dialogue with memory
    Resources
    • OpenAI Cookbook (github.com/openai/openai-cookbook)
    • Anthropic prompt engineering guide
    • DeepLearning.AI 'ChatGPT Prompt Engineering for Developers' course
    • Simon Willison's blog and talks on LLM applications
    Milestone

    You can build a multi-turn chatbot with streaming responses, tool use, and conversation memory using raw APIs.

  2. RAG Architecture & Vector Databases

    4 weeks
    Goals
    • Design end-to-end RAG pipelines: document ingestion, chunking strategies, embedding models, vector storage, and retrieval
    • Implement hybrid search (semantic + keyword) with re-ranking for high-relevance retrieval
    • Build evaluation frameworks for retrieval quality (recall@k, MRR) and generation quality (faithfulness, relevance)
    Resources
    • LangChain RAG documentation and tutorials
    • LlamaIndex documentation (data connectors, indices, query engines)
    • Pinecone learning center on vector search fundamentals
    • Research papers: 'Retrieval-Augmented Generation for Knowledge-Intensive NLP Tasks' (Lewis et al.)
    Milestone

    You can build a production-grade RAG system over a corpus of PDFs, codebases, or knowledge bases with measurable quality metrics.

  3. Orchestration Frameworks & Agentic Patterns

    4 weeks
    Goals
    • Master LangChain/LangGraph for building complex multi-step copilot workflows with routing, branching, and state management
    • Implement agent patterns: ReAct, plan-and-execute, tool-use loops, and multi-agent coordination
    • Build copilot features that can take actions - query databases, execute code, call APIs, update records
    Resources
    • LangChain Expression Language (LCEL) documentation
    • LangGraph tutorials on stateful multi-actor applications
    • Andrew Ng's 'Building Agentic RAG with LlamaIndex' course
    • OpenAI function calling and Assistants API documentation
    Milestone

    You can build an agentic copilot that plans, retrieves context, uses tools, and produces multi-step solutions with error handling.

  4. Production Systems, Evaluation & UX

    4 weeks
    Goals
    • Deploy copilot systems with proper observability: tracing, logging, cost tracking, and latency monitoring
    • Build robust evaluation pipelines with automated LLM-as-judge, human annotation workflows, and regression detection
    • Design copilot UX patterns: inline suggestions, contextual chat, streaming UIs, and graceful error/fallback states
    Resources
    • LangSmith / LangFuse documentation for LLM observability
    • HuggingFace Evaluate library and OpenAI Evals framework
    • Vercel AI SDK documentation for building streaming React frontends
    • Industry case studies: GitHub Copilot architecture talks, Microsoft Copilot engineering blogs
    Milestone

    You can deploy, monitor, evaluate, and iterate on a production copilot system serving real users with confidence in quality and cost.

  5. Advanced Topics & Portfolio Capstone

    4 weeks
    Goals
    • Explore advanced topics: fine-tuning for copilot behavior, semantic caching, model routing, guardrails, and red-teaming
    • Build a portfolio-worthy copilot application end-to-end for a specific domain (legal, code, sales, healthcare)
    • Prepare for interviews by practicing system design for copilot-scale applications
    Resources
    • OpenAI fine-tuning guide and best practices
    • Guardrails AI / NeMo Guardrails for safety layers
    • Together.ai and Anyscale for open-source model hosting
    • System design interview resources adapted for AI-native applications
    Milestone

    You have a production-quality copilot project in your portfolio and can confidently architect and discuss copilot systems at a senior engineering level.

Practice Projects

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